Abstract :
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
