Abstract: The optical receptacle includes an incidence surface and an emission surface. Light emitted from the light-emitting element includes a first light beam and a second light beam. A first light flux of the first light beam that is emitted at ±10 degrees with respect to the optical axis is focused on the central light beam of the first light flux after it is emitted from the emission surface. A second light flux of the second light beam that is emitted from an emission point at ±10 degrees with respect to the optical axis is controlled to be located on the opposite side of the emission point side with respect to the central light beam of the first light flux after it is emitted from the emission surface, the emission point being an end portion of one light-emitting surface on the plane.

Abstract: A communication module including a primary radiator for transmitting an electromagnetic flux, and an electromagnetic flux controlling member for controlling a travelling direction of the electromagnetic flux sent from the primary radiator. The electromagnetic flux controlling member includes an incidence surface and an emission surface. The incidence surface and the emission surface are configured such that the electromagnetic flux emitted is expanded than the electromagnetic flux transmitted from a focal position of a reference lens optimized to collimate the electromagnetic flux from the primary radiator and emitted after incidence on the reference lens on a basis of an emission angle of the electromagnetic flux emitted from the primary radiator, a dielectric constant of the electromagnetic flux controlling member, and an arbitrarily set focal length of the electromagnetic flux controlling member.
