摘要：

The proposed TW-PA modulator has a thin intrinsic layer (a 0.2 mu m thick strained InGaAlAs (13nm)/InAlAs (5nm) MQW) and short interaction length (200 mu m). The optical 3dB modulation bandwidth exceeds 50GHz and the driving voltages for the 15dB extinction ratio are 1.7 and 1.9V for TE and TM modes respectively, at 1.55 mu m wavelength.
