Abstract
A method for amplifying an input optical signal includes the following steps: providing a light-emitting transistor device having a base region between collector and emitter regions; applying electrical signals with respect to the base, collector, and emitter regions to produce light emission from the base region of the light-emitting transistor device; and applying the input optical signal to the base region of the light-emitting transistor device to produce an amplified optical output from the base region.
