A report from CLEO 2017

Last week I spent some super time at CLEO 2017 in San Jose, California.

The conference as usual was very good and I will write about my favourite talks. There were some new and exciting events that made the conference more special. I gave my own short course on FEM at CLEO now for the 4th time, so that was fun.

So the talks first: I found Dr. Nergis Mavalavala‘s plenary talk on LIGO very cool. It is good to hear about fields where Optics is being used for cutting edge research, while the field is not primarily Optics. Astrophysics has long been an interest for me, so no huge surprises that I liked this talk. I was excited to learn that India is planning a LIGO type detector too!

The session on halide perovskite lasers and particularly the talk by Tze Chien Sum, Nanyang Technological University, Singapore was excellent to understand the current state of the art in these lasers and the challenges facing the field now.

The application and technology review on Supercontinuum Generation (SCG) was another great session: focus on SCG theoretical and experimental development was covered in talks including a historical perspective. It gave a sense of how an entire research field evolved and is still current! My favourites talks in this session were by Alan Willner ( a past president of OSA) on Structured Light using Spatial, OAM and Wavelength Domains for Terabit/sec Communications; and by Adam Devine of  Fianium, who spoke on Supercontinuum  Laser Sources Future Await Wide Applications.

The best technical part however for me was the Bright Idea competition sponsored by Quantel. I was asked to judge the competition with 3 others. We heard 4 talks, and each was amazing. In 15 minutes the competitors took us from the basics in their fields to the research frontier, and what they were going to do, why this was important and the innovation in their approach.
I learned about photo acoustic imaging of the brain, quantum optics (a topic I have always found a bit difficult) and aerodynamics research.  It was an incredibly difficult decision to make amongst the 4 finalists, but eventually the winner was from University of Otago, Harald Schwefel who spoke on Photon Triplets for Quantum Optics and Secure Communication. Next year I think I might submit an entry into the competition as well!

Now to the exciting new events: there was a workshop on unconscious bias, the first I attended. We were shown images and we discussed our reactions to these… this led to realising what are the underlying, unconscious but almost immediate reactions we have, how we categorise or classify.  How we react to people and see someone as warm and relatable or as competent and capable, while someone else as untrustworthy/incompetent. It was a revelation! I would highly recommend trying one of these if you can.

I was stunned to realise how much the colour of a person’s skin meant to me when I judged the person as warm or not. That led me to think if I was then letting this influence my decisions on students, on hiring people, on my volunteer work…

I came away with much to think about from CLEO: both technical and also personal.
