Patent ID: 8324644

Claim:
An optical functional element comprising: a substrate; a semiconductor element portion that includes a first part of a semiconductor multi layer structure formed on the substrate; and a light emitting element portion that includes a second part of the semiconductor multi layer structure and light emitting element structure formed on the second part of the semiconductor multi layer structure, wherein the semiconductor multi layer structure includes a semiconductor element structure formed by p-type semiconductor layer and n-type semiconductor layer in order of npn or pnp on the substrate and a light reflective layer formed of alternating layers of a first semiconductor layer and a second semiconductor layer on a side of the semiconductor element structure opposite to the substrate, a refractive index of the first semiconductor layer is differ from a refractive index of the second semiconductor layer, and the semiconductor multi layer structure is divided into the first part and the second part by a groove formed in a cross direction of a grown face of the semiconductor multi layer structure.
