Semiconductor light emitting device and semiconductor light emitting apparatus

摘要

A semiconductor light emitting device comprises: a stacked body of semiconductor including an active layer; a ridge stripe protruding and extending in a first direction on a first major surface of the stacked body; dummy ridges protruding on the first major surface of the stacked body on both sides of the ridge stripe; and a slit formed on the first major surface of the stacked body. The ridge stripe includes at least a portion of a waveguide that guides light emission generated by injected current. The slit extends along a second direction which crosses the first direction, and divides one of the dummy ridges.
