1. An optical receptacle configured to be disposed between one or more vertical cavity surface emitting lasers disposed on a substrate and one or more optical transmission members, the optical receptacle being configured to optically couple the one or more vertical cavity surface emitting lasers and an end surface of the one or more optical transmission members, the optical receptacle comprising:
a first optical surface configured to allow incidence of light emitted from the one or more vertical cavity surface emitting lasers;
a second optical surface configured to emit, toward the end surface of the one or more optical transmission members, light entered from the first optical surface and transmitted inside; and
a reflection surface configured to internally reflect, toward the second optical surface, light entered from the first optical surface,
wherein the first optical surface is disposed such that a central axis of the first optical surface is tilted with respect to an optical axis of the one or more vertical cavity surface emitting lasers, or that the central axis and the optical axis are in parallel without coinciding with each other,
wherein an inclination angle of the reflection surface with respect to an optical axis of light entered from the first optical surface is 49 to 52°.
