ABSTRACT:
A switched multi-channel optical receiver having N metal-semiconductor-metal photo-detectors receiving different optical signals, N switches selectively applying a bias voltage to one of the photo-detectors, and a single amplifier. All the elements are integrated in an InP opto-electronic integrated circuit. The switching to a single amplifier allows a reduced number of components.
