ABSTRACT:
An injection semiconductor laser having an active region normal to the reflecting surfaces includes an ohmic metal film on the side of the heat sink near the active region. The ohmic metal film is plated with a layer of a thermally conductive material. The shape and dimensions of the plated layer are selected to protect the laser from being damaged when the laser device is bonded to the heat sink, and also to prevent light rays emerging through one of the reflecting surfaces from impinging on the surface of the heat sink.
