Edge-emitting Semiconductor Lasers – in-plane lasers - RP …
网页Semiconductor lasers can be grouped into two classes: Edge-emitting lasers (also called in-plane lasers), where the laser light propagates in a direction along the wafer surface of the semiconductor chip, from which the laser is made. The light is usually reflected or coupled out at a cleaved edge.
