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