Abstract
A light emitting device according to an embodiment of the present disclosure includes: a semi-insulating substrate having a first surface and a second surface that are opposed to each other; a first semiconductor layer that is stacked on the first surface of the semi-insulating substrate and has a lattice plane non-continuous to the semi-insulating substrate; and a semiconductor stacked body that is stacked above the first surface of the semi-insulating substrate with the semiconductor layer interposed in between. The first semiconductor layer has a first electrical conduction type. The semiconductor stacked body has a light emitting region configured to emit laser light.
