ABSTRACT:
By using a monolithic sheet of photodetector semiconductor and creating a series of isolated individual optical paths, the performance of a multiple channel coupler can be improved. Multiple photodetectors are fabricated on the substrate, yielding electro-optically matched devices. By using common connection of the photodetectors and common connection of the optical sources, the pin-per-channel count is minimized.
