通过在光子晶体上叠加受控无序，我们进行了紧凑、灵敏的高分辨率光谱仪的数值模拟和制作。这将同时创建面内散斑并抑制面外散射。我们进行了二维和三维数值模拟，以证明在这种无序增强的光子晶体结构中，与完全无序结构相比，在分辨率没有任何妥协的情况下，面外散射减少，吞吐量提高。
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.
