입력광 이동 및 도파로 폭 변화에 따른 1 x 2 다중 모드 간섭기의 최적화

초록

Simple simulation of 1x2 MMI device with an effective index method has been utilized to optimize the field excitation coefficients by shifting the position of input waveguide and by changing the output waveguide width. Additionally, shorter MMI length is also proposed to obtain better characteristics with more elaborate calculation of in the guided-mode propagation analysis (MPA).
