Semiconductor optical amplifier for amplifying an incoming optical signal has an optical amplifying area (OAA) on a semiconductor substrate and a pump laser to generate an optical pump wave for the OAA

摘要

A pump laser (PL) (60) and an optical amplifying area (OAA) (20) fit on a semiconductor substrate in such a way that a pump wave (PW) (80) spreads parallel to the substrate's surface and radiates into the OAA. The PL and the OAA fit alongside each other so that the PW radiates directly into the OAA.
