摘要：
A ridge-waveguide In0.53Ga0.47As/InP multiple quantum well (MQW) electroabsorption modulator operating at a wavelength of 1.52 μm is demonstrated. This modulator exhibits large polarization dependent electroabsorption behavior which favors the modulation of the TM mode. At a reverse bias of 10 V, the modulator has a 24.5 dB extinction ratio for the TM mode while that for the TE mode is only 11.1 dB. Polarization dependent saturation of absorption has been observed in this device for incident optical power levels of less than 1 mW. © 1990 IEEE
