Abstract: A communication module of the present invention is a communication module including a transmission/reception part and an electromagnetic flux controlling member. The electromagnetic flux controlling member includes a first surface and a second surface. The first surface of the electromagnetic flux controlling member includes a first region including an incidence portion of near-axis light to be converged at a first focal position, the near-axis light being located closest to a central axis of the electromagnetic flux controlling member, and a second region disposed in a region surrounding the first region and including an incidence portion of light to be converged at a second focal position when parallel light is entered from the first surface and emitted from the second surface. The second focal position is located at a position farther from the electromagnetic flux controlling member than the first focal position.

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.

Abstract: An optical receptacle includes an optical receptacle main body and a filter. The optical receptacle main body includes a first optical surface, a second optical surface, a third optical surface, and a reflecting surface. The filter includes a first filter that reflects light of a first wavelength and allows light of a second wavelength to pass therethrough, and a second filter that reflects the light of the second wavelength and allows the light of the first wavelength to pass therethrough. The filter is disposed on the optical receptacle main body such that the first filter or the second filter makes intimate contact with the reflecting surface. A second central axis of the second optical surface do not coincide with a light axis of a light-receiving element. A third central axis of the third optical surface do not coincide with a light axis of a light-emitting element.

Abstract: The problem addressed by the present invention is to provide: an optical receptacle that can be easily positioned with a photoelectric converter having a light-emitting element and a detection element. In order to solve the problem, an optical receptacle is provided, said optical receptacle being positioned between a light transmission medium and a photoelectric converter having a substrate, a photoelectric conversion element and a detection element, and the purpose of the optical receptacle being to optically couple the photoelectric conversion element and the end surface of the light transmission medium. The optical receptacle comprises a filter, a holding member for holding the filter, and a receptacle body. In the optical receptacle the holding member and the receptacle body are separate bodies, and the filter reflects towards the detection element side, as monitor light, part of the light emitted from the photoelectric conversion element, and transmits the remainder as signal light.

Abstract: This optical receptacle has a first optical surface, a reflection surface, a second optical surface, a light separation part, and a third optical surface. On the first optical surface, light from a photoelectric conversion element is incident. The reflection surface reflects the light incident on the first optical surface. The second optical surface allows the light reflected by the reflection surface to be emitted toward an end surface of an optical transmission body. The light separation part separates the light reflected by the reflection surface, into monitor light and signal light. The third optical surface allows the monitor light to be emitted toward a detection element. The light separation part includes divided reflection surfaces and divided transmission surfaces. At least one of the divided transmission surfaces includes one or more widened portions each having a width larger than those of the other divided transmission surfaces.
