Abstract:
1. A reflective semiconductor optical amplifier (RSOA) comprising: an active region performing amplification; a p-type electrode supplying current to the active region; an anti-reflective coating facet through which a signal is input and output; and a high-reflective coating facet reflecting a signal, wherein the anti-reflective coating facet and the high-reflective coating facet are formed at both ends, respectively, of the RSOA; and the p-type electrode is divided into a first portion and a second portion with a predetermined gap between the two portions, wherein a direct current for squeezing a signal is supplied to the first portion of the p-type electrode, and a bias current and a radio frequency current for amplifying and remodulating a signal are supplied to the second portion of the p-type electrode.
