Abstract

We performed numerical simulation and fabrication of a compact and sensitive high-resolution spectrometer, by superimposing controlled disorder on a photonic crystal. This simultaneously creates an in-plane speckle and suppresses out-of-plane scattering. We perform two- dimensional and three- dimensional numerical simulations to demonstrate reduced out-of-plane scattering and enhanced throughput in such disorder-enhanced photonic crystal structures compared to completely disorder structures without any compromise on resolution.
