FDTD를 이용한 진행파형 Ridge-type CPW 다중 양자 우물 전계 흡수 변조기 분석
Analysis of Traveling-wave Ridge-type CPW MQW EA-modulator using FDTD
초록
Among many optical modulators, we are interested in traveling-wave(TW) multiple quantum well(MQW) electro-absorption modulator which can be used for wide-band applications, covering DC to 30GHz or higher frequencies. In this study, we simulate a 1.3mm InGaAs/lnGaAsP TW MQW EAM using the 3D Finite Difference-Time Domain (FDTD) method. We identify that several geometric factors affect Microwave charateristics. Our calculated data provide useful information to optimize and fabricate ridge-type TW CPW EAM.
