Abstract
An optical switch includes: a photothyristor that is switched from an off state to an on state by incident light; a light-emitting element that emits outgoing light when the photothyristor is in the on state; and a tunnel junction layer or a III-V compound layer having metallic conductivity. The tunnel junction layer or the III-V compound layer is disposed between the photothyristor and the light-emitting element.
