ABSTRACT:
A device for amplifying an input optical signal includes an optical amplifier having a gain control region in which the input optical signal is amplified, a first detecting region for detecting the input optical signal, and a second detecting region for detecting an amplified optical signal. The gain of the optical amplifier is controlled by a gain control signal from a signal source. A controller, responsive to detecting signals from the first and second detecting regions, produces a source control signal which is supplied to control the signal source.
