초록
Arrayed waveguide grating의 스펙트럼을 해석하기 위해 Fresnel Kirchhoff diffraction 식과 Fraunhofer diffraction 근사식을 이용하여 실제로 제작되는 16채널 및 40채널의 arrayed waveguide grating에 대해 적용해 보았으며 Fraunhofer diffraction 근사식을 적용할 때 생기는 문제점을 모델별로 도출하였고 그 오차를 실제의 공정오차와 비교하였다.
Abstract
We performed the spectrum analysis of arrayed waveguide grating using Fresnel Kirchhoff diffraction formula and its approximated Fraunhofer diffraction equation and applied both methods to 16 channel and 40 channel models. We presented the spectra and found out the limitations of Fraunhofer diffraction in analysis of arrayed waveguide grating and compared the errors coming from Fraunhofer diffraction approximation and due to imperfection during the fabrication process.
