Paper Abstract

We present mushroom-type TWEAM, which has improved velocity mismatch, with optimized impedance match compared to conventional modulators by reducing the distance between signal and ground metal line. In this paper, the layer structure of mushroom-type TW MQW EAM is designed for the operation of 1.55 um and optical index of active layer is designed to be 3.6. Also, we simulate an 1.55 um InGaAs/InGaAsP traveling-wave multiple quantum well electro- absorption modulator using 3D Finite Difference Time Domain method. Also, we investigate microwave characteristics in detail.
