ABSTRACT:
The specification describes a discriminating photodiode for detection of 1.55 .mu.m signals used in wavelength multiplexed systems operating with 1.3 .mu.m and 1.55 .mu.m wavelengths. The device uses a semiconductor layered structure to absorb photons from the 1.3 .mu.m signal, and annihilate the photogenerated carriers, while passing the 1.55 .mu.m light to a photodetecting junction beneath the layered structure.
