Inspiring tour The Ottawa Hospital Cancer Centre for #medphys Carleton Grad Studies students - much #innovation by physicists! Thanks @MillerMacP for great stories + the opportunity for learning outside the classroom

After a while, we've finally created a twitter account for our research group: Boyd NLO Research Group. Follow to keep track of our work and events! (Please RT to help get the word out!)

We experimentally demonstrate omni-directional phase matching via four-wave mixing in zero-index silicon waveguides exhibiting phase-free propagation in the infrared range. #POM20ju #POM20LM Photonics Online Meetup uOttawa | Innovation CRPuO

The Boyd group will have quite the showing this year at #OSAPhotonics20 Advanced Photonics Congress next week, with 11 total talks including a tutorial by Bob himself! If you want to see these talks, registration is completely free: osa.org/en-us/meetings…

By using zero-index silicon waveguides exhibiting phase-free propagation in the infrared range, we experimentally demonstrate multi-directional phase matching by using four-wave mixing as a proof of concept. #POM21ja #POM21meta Photonics Online Meetup

My last #photonics Boyd NLO Research Group paper as lead is finally out, and it's an Editor's Suggestion at Physical Review Letters! We use zero-index waveguides to study NLO phase-matching. I started this project in Mar '14 & you finally get to see it thanks to Justin Gagnon! journals.aps.org/prl/abstract/1…

Experiments in Dirac-cone metamaterials present the first observation of direction-independent phase matching in a medium where phase matching is relevant for parametric nonlinear optical processes go.aps.org/3yIxJWA
