摘要：

We demonstrate low-loss monolithic integration of a 3 dB waveguide coupler with twin-photodetectors using large mode size guides, mirror coupling, and low-capacitance lateral detectors. Waveguide-mirror integration introduces only ≈1 dB optical insertion loss at 1.54 μm wavelength, compared to top-illuminated detectors. Full balanced operation of the monolithic circuit with 33 dB local oscillator intensity noise suppression is demonstrated. © 1990 IEEE
