Abstract :
The authors have monolithically integrated an optical front-end on InP for balanced, polarization-diversity coherent lightwave reception which is only 1.3-mm long. Low on-chip insertion loss (<4.5 dB) and balanced photoresponse (1.05:1 or better) are achieved at 1.5- mu m wavelength using straightforward, regrowth-free fabrication. Low-capacitance photodetectors (>
