Digital Firsts

Since I wrote about my first international online workshop experience at the start of the summer, I can report back, unsurprisingly perhaps, to say that a majority of my meetings have shifted online. It’s been a blur of Google Meet, Zoom, Teams, Webex, Remo and other online spaces used to connect with family, friends and colleagues. In July, Shashwath Bharadwaj hosted me on the SPIE Facebook Career Lab for a week long residency to discuss these online meeting experiences. I ran a survey with about 40 of the group Members, and found that amongst respondents aged 25-35, most were meeting online for work at least 2-3 times a week. This time last year for me, it was probably closer to 2-3 per month for work!

Repurposing furniture and space for my home online meeting setup

The inspiration for this blog has shifted. The reflex for reporting a trip and travel, which physically took me out of context, has evaporated. I had planned to write earlier about my August travel to Sunny San Diego and the paper that I was going to be presenting at the SPIE Optics Education and Outreach conference, but that went digital too. The paper was published and presented, virtually of course, as part of the SPIE Digital Forum. This was a first for me, which involved a combination of writing a paper, adapting it to present on a Slack channel, pre-recording a talk following expert advice (see Jean-Luc Doumont’s SPIE webinar online), setting up my home space to present my work. A shift into a new normal!

The reception of the paper has been pleasing. My SPIE Slack channel had almost 70 people following my experimentation with live “Slack chats“, to translate the paper to this text-chat-platform. As a follow-up, I was invited by Excelitas‘ global training and development program to share this work with colleagues in the organisation. This turned out to be my largest live technical audience to date, with almost 100 people from 3 continents on the web. People have been interested in discussing how skills can be transferred between teaching and work environments, lessons learnt from internship programs, and the need for programs for training in industry with models for inclusivity and equity at their core. I appreciated the sense of appreciation from my colleagues and the wider community.

The need to connect with the professional community has accompanied me throughout the summer. I have had the pleasure to e-meet many new people through digital networking. The need to learn new tools to make new connections were fast tracked by my responsibilities in other volunteering roles! My governance roles with the SPIE took a digital turn, and opened new and wonderful ways to connect and progress on this aspect of my volunteer work for students, early career professionals and education. Closer to home in Montréal, the next big event ahead is the 4th Montreal Photonics Networking Event. This is happening on a screen near you, on Friday 23rd October! If you have read this far, you are invited to register!

It’s certainly an exciting time to be learning, collaborating and making progress in the fields. I wish to sign off with a note of appreciation to the technologists that have permitted an accelerated digital transition to this new online reality. In my research days, I taught school students a class called Communicating with Light – developed independently from Prof. Polina Bayvel’s excellent Clifford Patterson lecture. We explored how the science and technology of photons and electroncs, photonics and electronics respectively, were used in getting our internet to function. The internet is made possible by the physical infrastructure of fibre optics cables laid around a world and improvement to computer chips to make sense of the digital information leaping across continents. The reality that we’ve glided into a new scale of this digital age is testimony to how important the fundamental sciences and applied technology have been in helping this happen. As I mark this post in the Canadian Thanksgiving weekend, I reflect on that there is a lot to be grateful, not least your attention!

The 2020 International SPAD Sensor Workshop

Last week I attended the 2020 International SPAD Sensor Workshop. This was an international meeting that did not involve me travelling around the world to Edinburgh, Scotland; indeed, the entire workshop was held virtually owing to the Covid-19 crisis.

The new “normal” for meetings

Single-photon avalanche diodes (SPAD) are a mature photonics technology. Today, there is a large interest from the private sector, reflected by a majority (55%) of attendees coming from the industry and many student research projects conducted in collaboration with advanced R&D departments. The workshop covered a broad range of topics, from current technology trends for manufacturing and testing devices, as well as applications and systems studies.

Current developments are being driven by a number of biomedical imaging applications, such as PET and CT scanners, through to applications in the many segments of the commercial LIDAR market.  These bigger markets are bringing larger manufacturing centres closer to developing this technology, such as ST, Canon and Panasonic. This was all the more evident by the overwhelming number of contributions in talks, sponsors, and funded research students linked to high-volume CMOS manufacturing .

A significant amount of progress has been made since the seminal review on the subject from 2008 (via IEEE Explore) and early patents from ST on CMOS based SPAD (via Google Patents). Many of the talks explored the scaling of the technology using advanced CMOS manufacturing techniques for the production of SPAD arrays. Highlights to me, from the applied technology aspect, were the incorporation of test structures to measure the properties of these sensitive devices (more to follow this year from Alexander Zimmer at Xfab) and the demonstration of megapixel SPAD sensors (via OSA Optica). There were also many novel architectures for custom devices, to improve high-efficiency detector arrays in silicon technologies (via IPT), adapting material processing to achieve more efficient designs (delta-doping via SPIE DL) and going beyond silicon using germanium (via Nature Communications).

Live from the conference at home in Canada

The online format was original. The organising committee proposed an online hybrid platform to ensure presentations and content were accessible throughout the week. Live presentations were done on Blackboard Collaborate and streamed live at British Standard Time. This made for a very early start on day #1 : 4 am ET to be precise! The presentations were recorded and made available on a Microsoft Teams channel afterwards. This channel was open to all attendees to chat, and pre/re-view posters and talks. The platform also hosted two live poster sessions, with small breakout rooms to meet and discuss research in a more informal setting. The organisers even scheduled coffee breaks. It took some organising to connect with people virtually, but the closed group guaranteed that interaction was genuine. The serendipitous meetings with attendees, presenters, and organisers at events was missed compared to the real-life experience. Kudos to the 20-strong person team operating in the background that contributed to this event running so smoothly!

SPIE Optics + Photonics 2018

I’ll be attending the 2018 SPIE Optics + Photonics congress this coming week. This will be my second time in San Diego in two years and I’m excited to be returning to what has been one of my favorite meetings on the photonics conference circuit.  If you are attending and I haven’t spoken to you yet, then please get in touch through the contact page or LinkedIn! See below for an abridged schedule of talks, training and meetings as well so that you can get an idea of where to find me!

I am particularly excited about all of the Optics Educators and Outreach aspects of this congress. My week is filled with exciting outreach and education activities. I will be judging at the Outreach Olympics on Sunday (where I myself presented two years ago!), presenting alongside expert Photonics Educators Mike McKee and Nancy Magnani (there is still time to register at this link!). I will also be attending the Fifth Optics Education and Outreach Conference. I will be presenting two papers on outreach and public engagement activities that I did when I was previously in Southampton’s Optical Engineering and Quantum Photonics group. They are on Wednesday, and I hope to see you there!

Hope to see you there!
