Abstract
A light emitting element array includes a single semiconductor substrate, a plurality of semiconductor elements, which are formed on the single semiconductor substrate, and each of the semiconductor elements including a first distributed Bragg-reflector, an active layer formed over the first distributed Bragg-reflector, and a second distributed Bragg-reflector formed over the active layer. The array includes an electrode pad formed over the second distributed Bragg-reflector and a wiring formed at least partly over the second distributed Bragg-reflector and extending from the electrode pad toward the semiconductor elements. The semiconductor elements include a first semiconductor element, configured to emit laser light, and a second semiconductor element configured not to emit laser light and disposed at a position which is shorter distance along the wiring from the electrode pad than a distance along the wiring from the electrode pad to a position of the first semiconductor element.
