摘要

研究了高斯入射光束的高效导模共振。在波导腔内移动光栅耦合器的光栅齿位置，使耦合孔径内的耦合系数增大，从而使谐振最大化。设计了器件，并对其耦合特性进行了数值模拟。

An apodization method for grating coupler in waveguide cavity

High-efficiency guided-mode resonance for an incident beam of Gaussian profile was studied. Grating-tooth positions of grating coupler were shifted in a waveguide cavity to apodize the coupling coefficient within a coupling aperture to maximize the resonance. Devices were designed and their coupling characteristics were numerically simulated.
