We investigate the physics and applications of nanoscale photonic structures. In particular, we are interested in light confining structures that can slow down, trap, enhance and manipulate light. Photonic structures can enhance light-matter interactions by orders of magnitude.The applications of the devices that we design, fabricate and demonstrate are numerous: on-chip light modulation (optically and electro-optically) and detection, networks on-chip, nonlinear phenomena, multi-material devices and platforms, microfluidics, basic physics, etc.
