High efficiency devices based on slow light in photonic crystals.

摘要

Photonic crystals have allowed unprecedented control of light and have allowed bringing new functionalities on chip. Photonic crystal waveguides (PCWs), which are linear defects in a perfect crystal, have unique features that distinguish these waveguides from other waveguides. The unique features include very large dispersion, existence of slow light, and the possibility of tailoring the dispersion properties for guiding light. In my research, I have looked into some of the challenges in using slow light in PCWs. I have also demonstrated a sample application of refractive index sensing to show the promise the field of PCWs hold.
