Abstract
A method to control an optical receiver implemented with a semiconductor optical amplifier (SOA) is disclosed. The SOA has a p-n junction operable in a PD mode when it is supplied with a zero or reverse bias. The SOA detects the magnitude of the incoming light and the driving current supplied thereto is adjusted based on thus detected magnitude of the incoming light such that the outgoing light provided to the PD has a magnitude within a preset range.
