Summary:In conclusion, we have presented two-wavelength demultiplexing
photodiodes utilizing multiple quantum well material so that for
wavelengths as close as 15 nm there is less that -12 dB of crosstalk. We
produced two devices, one that operates at 810 and 825 nm, and the other
at 840 and 855 nm. The devices may be packaged inexpensively as for
ordinary photodetectors
