BOSS visits Gooch & Housego, Torquay




Bristol Optical Students Society makes first industry visit to Gooch & Housego, Torquay.


On Tuesday 29th November, Bristol Optical Student’s Society, a.k.a BOSS, held its first ever industry excursion, bussing a mix of 11 students and post-docs down to Gooch & Housego’s Torquay site. Leading the world in high-quality optics manufacturing, the UK-based G&H has supplied the technology that underpins the foundations of our modern networked world. Having recently expanded their Torquay facility as well as being awarded the Queen’s Award for Enterprise for their highly successful Fiber-Q device, BOSS was keen to head down to the Devonshire coast to find out the secret to their success.

The visit started with an overview of the historical and current state of the company, before a tour of the company’s manufacturing facilities. From the hand-fabrication of precision fused-fibre waveguides, to the assembly of bespoke optics modules, the tour visited each stage of the company’s manufacturing process, exhibiting the large variety of optical systems they produce. After lunch was generously provided, the day was concluded with an informal networking session with members of G&H’s staff and management. Discussing everything from business strategies to commercial quantum computation, this session allowed the visitors to discuss their personal interests in the industry, as well as giving G&H an opportunity to ask quantum engineering researchers about current research and the future of their field.

Bristol Optical Students Society would like to thank all of Gooch & Housego Torquay for a great day, especially Tom Legg for helping organise the visit. If you are interested in joining BOSS and finding out about the many academic, professional and extracurricular opportunities available (for free) to BOSS members, please email BOSS.Bristol.OSA@gmail.com or like our Facebook page at https://www.facebook.com/lightisboss/.

My experiences at the Epixfab summer school 2016

by Giacomo Ferranti



On the week between Monday 28th of August and Friday 2nd of September, I attended a summer school organized by Epixfab at Gent University in Belgium.
The event was mainly focused on classical integrated photonics. Most of the talks on the first two days were meant to introduce the most common integrated components and to present the state of the art of their specifications. I personally found particularly useful the talk given by Dr. Laurent Vivien (Paris-Sud University, France) on integrated germanium photo-detectors.
Many of the speakers talking on the following days were from companies like HP, IMEC, Luxtera or ST Microelectronics, but there were also interesting talks from academics like  Prof. Jose Capmany, from Universitat Politècnica de València in Spain.
Prof. Mark Thompson who is one of the senior academics at the Centre for Quantum Photonics was a speaker too. He gave a very good talk on quantum applications of integrated photonics, which was highly appreciated by the audience.
There was also a poster session on Tuesday evening. I presented a poster about on-chip homodyne detection and won a shared second prize for the best poster.
Finally, we had a taster session of simulation software on Friday. Available software included PhoeniX, Fimmwave and IPKISS.
This was overall an extremely useful experience, which made me much more aware of the technologies available for the silicon platform and helped me learning how to relate my own project to work being done in different fields.

What it was like attending NUSOD in Australia


By Gerardo Villarreal Garcia

From 11 to 15 of July I attended the 16th International Conference on Numerical Simulation of Optoelectronic Devices (NUSOD) hosted this year by the University of Sydney, in Australia.
The event took place in recently inaugurated Sydney Nanoscience HUB, a multi million high-tech research and teaching facility funded by the Commonwealth Education Infrastructure Fund and the University of Sydney.

The NUSOD conference is a space where theory and practice meet in order for researchers to discuss the progress in numerical simulations and practical applications in photonics and electronics.The topics discussed during the week included simulations on semiconductor lasers, LEDs, photodetectors, solar cells, integrated photonics, etc. Four days in total of talks and one final day for practical workshops on how to model optic and optoelectronic devices using software such as COMSOL Multyphysics, Crosslight and Synopsys RSoft. You can consult the list of talks and posters in this link.
The conference began with the customary statement of Acknowledgement of Country, which the University of Sydney recognises and pay respect to the traditional owners of the land, followed later by a session in charge of australian colleagues. The first talk was an invited paper presented by  Benjamin J. Eggleton who spoke on the future of integrated nonlinear photonics and the harnessing of light-sound interactions.

During the afternoon of the first two days a poster sessions took place. I presented a poster on a simulation of fabrication yield and detection efficiency enhancement of a superconducting nanowire single photon detector (SNSPD) fabricated on a silicon-on-insulator ring resonator. The poster was later awarded with the “best poster” prize.

Because a trip to Australia without koalas and kangaroos is simply incomplete, on the third day we visited the Taronga Zoo, a fantastic place with not only a huge variety of species but also a amazing view of the city centre and its skyscrapers.

Later that night we had dinner in the Italian Village, a fancy restaurant in the Circular Quay with a spectacular view of the Opera House. After an appetising dinner and some engaging conversations with other conference attendees, Prof. Jim Piper, from Macquarie University, gave a speech about the first years of laser physics in Australia and its development until today.
Overall, I consider the event was a great opportunity to engage with people using the same tools I work with, to learn about new methods and new approaches to model electro optical devices and phenomena.
I would like to thank to the Alumni Foundation for the support they provided to make this trip happen.

Physics Lindau Nobel Laureate Meeting through my binoculars



 

Last year in September 2015 the Centre for Quantum Photonics (CQP), received an email from the European Commission (EC) inviting them to nominate a Marie Sklodowska-Curie fellow for a limited number of places to participate at the 66th Lindau Physics Nobel Laureate meeting. I was nominated by Jeremy O’Brien and Mark Thompson as an experienced researcher under the Marie-Curie ITN in Photonic Integrated Compound Quantum Encoding (PICQUE) project directed by Fabio Sciarrino (Uni Roma).
The selection process was two-fold, after my nomination by CQP1 I submitted my supporting application to the EC and by the end of October first evaluations were positive. The EC forwarded my application to the Lindau Nobel meeting selection committee and on the 1st of March 2016, I was emailed by the Lindau committee to confirm that my application was successful. I was one of 400 applicants from over 80 different countries to attend the 66th Physics Nobel Laureate meeting in Lindau with ~30 distinguished laureates. Three of the participants were current and/or former CQP members which was a great achievement for CQP2.

When I received the news, I was aware that it was a great achievement, however I didn't fully understand the significance of being one of the participants until the end of the week when I left. The meeting was nothing similar to any conferences or events that I have ever been to. Countess Bernadotte emphasised from the very first day at her opening speech that “Lindau spirit” is only accessible by physically being there. That became clearer to me every day and by the end of the week I understood what she meant. For me, it was the inspiration of the Nobel Laureates; being with them and talking to them during discussion sessions. And the city, which has seen many Nobel Laureates, signs of which you could see as soon as you left the train station.

Science discussions weren't just for the Nobel Laureates but also the young scientists too. Everyone was keen to exchange knowledge and culture, and make new friends and collaborations with other attendees. The meeting was more than a scientific conference, it was 400 young scientists dining together, going to the same lectures and participating in multiple social events. Events, such as science breakfast and Bavarian dinner, were the perfect occasions for networking. If the aim of the meeting was to transfer the knowledge and the enthusiasm of Nobel Laureates then it definitely achieved that and more.
Each science day, of which there were four in total, began with a science breakfast that we had either chosen in advance or were assigned according to our, or our sponsors', field of interest. Only a small portion of the participation cost is covered by our nominator, in my case that was the EC and the rest was covered by a variety of industrial and government sponsors. My first science breakfast was on Monday, hosted by one of the partners, the Austrian Federal Ministry of Science, Research and Economy. The topic was Quantum Information: From fundamentals to a New Technology. Emphasis was mostly on encouraging fundamental science so curiosity driven research will continue.
 
The rest of the day involved talks from Hiroshi AmanoTakaaki KajitaDavid J GrossCarlo RubbiaMartinus JG Veltman and Arthur B McDonald. It covered a broad range of topics from material science to high energy and particle physics. In the afternoon there was a panel on “Glimpses Beyond the Standard Model” in which some scientists from CERN (ATLAS, CMS and experiments) also participated through a video conference call. They gave an update on the experiments, and explained that they had achieved the planned strong luminosity (13 TeV) and are searching data for signature of heavy super-symmetric particles. Someone asked CERN what the 750 GeV signal meant in the recent experiments but they were unwilling to reveal anything (at 30:21 minutes.)The day ended with a wrap up discussion session from the morning's Nobel Laureates speakers.
On the second day, the science breakfast was about Excellence in Science and Sports hosted by Rolex. The morning lectures were more focussed and we listened to two Laureates who spoke about how and why they received their prizes in 2012 for their independent experiments on measuring and manipulating individual quantum systems. (Yes, I am talking about Serge Haroche and David Wineland -you can find their lectures here!) Theodor W Hänsch talked about light matter interaction and atom trapper William D Philips and Klaus von Klitzing and Gerardus ‘t Hooft were the last peakers before the afternoon discussion sessions. Klaus von Klitzing was as generous as always with his Nobel medal and brought it along so that we could hold it - this was my second time!

The third scientific breakfast organised by Mars Inc, was on Why does soft matter, matter? Talks were on gravitational waves by George F Smooth, followed by microscopy and biophysics talks by Samuel TingKurt WüthrichSteven ChuHartmut MichelJohann Deisenhofer and Robert Huber. At the end of the day, there were master classes chaired by one Nobel Laureate and 3-4 young scientists who discussed their research. I also attended the Quantum Information and Quantum Measurement session chaired by David J Wineland and we had a lecture from Vinton G Cerf (ACM AM Turing Award recipient in 2004, and also one of the “Fathers of the Internet”) on The Origins and Evolution of the Internet.
The last science day breakfast was hosted by McKinsey&Company Inc, on Decoding Science Leadership. Widespread topics were covered by the first two speakers, Stefan W Hell and Dan Shechtman, who talked about optical microscopy and the science of soap bubbles. Afterwards there were more biophysics lectures by Ada E Yonath and Martin Karplus. The morning talks ended with a lecture on the scientific approach to teaching physics by Carl E Wieman, a state of universe talk by Brian P Schmidt and a talk on the recollection of Las Alamos and the nuclear era by Roy J Glauber.
 
The afternoon session started with a panel discussion on Quantum Technology, namely Is Quantum Technology the Future of the 21st Century? The message was yes, there are already quantum technologies in use (such as atomic clocks) and it was unanimously agreed that this is an important task for this century. It was decided that the closest applications were in quantum sensing and it was agreed that big scale technologies, such as quantum computers will be difficult tasks to build. William D Philips said that it is important that we don’t decide on a single platform too quickly. Everybody’s contribution is important as a final platform for a quantum computer may well be a coupling of two or more ideas. I personally believe photons are precious particles for coupling but as Philips’ later discussions suggested, we do not know much about coupling two different platforms yet.
This was the end of the scientific days and the last day was a gateway to another nearby island, Mainau, where we had a panel discussion on The future of education in science. It was interesting to hear that in Israel, Dan Shechtman has initiated a programme for preschool kids to start talking about science. It is not so they understand the world as it is but is a good way to make kids look at everyday events from a different perspective and excite and interest them in STEM at an early age. Brian P Schmidt mentioned that he lost one of his favourite students as she found the University system to be un-collaborative while private companies provided better infrastructures to help develop new partnerships. Carl E Wieman is a keen advocate of science education and he discussed his research findings on science education and their efforts in changing the curriculum to make it more engaging for young people.
If I had not mentioned it before, Nobel Laureates were everywhere. The young scientists could talk to them and have a picture with them either after a discussion talk or even at the end of long tiring day after the social dinner or event. Here are some of the pictures I collected during my Lindau meeting:

I am sure I could write another few pages at least but I think it is time to stop here. If you are reading this blog as a potential participant of the Lindau meeting, please get in touch. As a Lindau alumnus I would be very pleased to help with any process.
