Disorder Enhanced-Photonic Crystal Based On-Chip Spectrometer

Bhupesh Kumar and Sebastian A. Schulz

Not Accessible

Your library or personal account may give you access

Abstract

We create a compact and sensitive high-resolution spectrometer, by superimposing controlled disorder on a photonic crystal. This simultaneously creates an in-plane speckle and supresses out-of-plane scattering. We perform 3D numerical simulations to demonstrate reduced out-of-plane scattering in such disorder-enhanced photonic crystal structures compared to completely random structures
