Slow and Stopped Light in Dynamic Moiré Gratings [PDF]
Phys. Rev. A 104, 013503 (2021), 2021 We investigate a theoretical model for a dynamic Moir\'e grating which is capable of producing slow and stopped light with improved performance when compared with a static Moir\'e grating. A Moir\'e grating superimposes two grating periods which creates a narrow slow light resonance between two band gaps.

Inverse Design and Demonstration of Broadband Grating Couplers [PDF]
IEEE Journal of Selected Topics in Quantum Electronics, 2018 We present a gradient-based optimization strategy to design broadband grating couplers. Using this method, we are able to reach, and often surpass, a user-specified target bandwidth during optimization.
