Abstract: The optical receptacle, which is disposed between one or more vertical resonator surface emitting lasers arranged on a substrate and one or more optical transmission bodies to optically couple the vertical resonator surface emitting lasers and end surfaces of the optical transmission bodies, has: a first optical surface on which light emitted from the vertical resonator surface emitting lasers is incident; and a second optical surface for emitting light, which enters the first optical surface and passes through the inside thereof, toward the end surfaces of the optical transmission bodies. The first optical surface is disposed such that a central axis of the first optical surface is inclined with respect to an optical axis of the vertical resonator surface emitting laser or the central axis and the optical axis are parallel to and do not coincide with each other.

Abstract: An optical receptacle is disposed between a light-emitting element and an optical transmission member and configured to optically couple the light-emitting element and the optical transmission member, the optical receptacle including an incidence surface configured to allow incidence of light emitted from the light-emitting element; and an emission surface configured to emit, toward the optical transmission member, light entered from the incidence surface and travelled inside the optical receptacle, the emission surface being an inner surface of a recess. The emission surface includes a first emission surface having a substantially spherical cap shape, and a second emission surface contiguous with the first emission surface, the second emission surface having a shape of a side surface of a substantially frustum shape.
