The present invention relates to a semiconductor optical amplifier device (10). According to the invention the semiconductor optical amplifier device (10) comprises - a plurality of active units (12, 14), each active unit (12, 14) comprising an active stripe structure (16, 18) of an optical amplifying medium and a current circuit (42) for injecting current into the corresponding active stripe structure (16, 18), wherein each active stripe structure (16, 18) extends from an input end (20) to an output end (22); and - an optical splitter device (34) for splitting incoming signal light and for distributing corresponding parts of the incoming signal light into the different input ends (20) of the active stripe structures (16, 18), wherein the optical splitter device (34) is configured to supply each active stripe structure (16, 18) with the same signals. The present invention further relates to a corresponding optical matrix switch (54). |
