摘要： An optical receptacle of the present invention includes: a first optical surface configured to allow light emitted from the photoelectric conversion element to enter the optical receptacle; a second optical surface configured to emit, toward the optical transmission member, the light having entered through the first optical surface; a positioning part configured to position an end face of the optical transmission member in such a way that the end face faces the second optical surface; and a region disposed at an optical surface in the optical receptacle. The region is configured in such a way that as a distance from an emission position of the light on the second optical surface to a center of the second optical surface increases, a distance from a position where the light intersects a central axis of the second optical surface to the second optical surface increases.

摘要： The optical module according to the present invention includes a photoelectric converter and an optical receptacle. The optical receptacle includes a first optical surface, a second optical surface, a transmission and reflection part, a recess, and a third optical surface. The transmission and reflection part is secured to the inner surface of the recess at a position that does not coincide with the optical path of signal light. The transmission and reflection part transmits the signal light incident on the first optical surface toward the second optical surface. The transmission and reflection part reflects the received light incident on the second optical surface toward the third optical surface. When viewed along a direction normal to a substrate, the optical path in the recess is inclined relative to the optical path between the second optical surface and the recess.

摘要： An optical receptacle having a first optical receptacle for transmission and a second optical receptacle for reception. The first optical receptacle has a first engaging section and the second optical receptacle has a second engaging section that engages with the first engaging section. The ratio between the intensity of incident light incident to the first optical receptacle and the intensity of emitted light emitted from the first optical receptacle is smaller than the ratio between the intensity of incident light incident to the second optical receptacle and the intensity of emitted light emitted from the second optical receptacle.

摘要： An optical receptacle capable of demultiplexing an optical signals to be transmitted and received without needing to place an optical functional member on an inclined surface and without needing to use an index-matching material is provided. The optical receptacle comprises: an optical splitter that allows transmitted light entering the optical receptacle from a light-emitting element to proceed to the emission surface toward an optical transmitter, and allows received light entering therein from the optical transmitter to proceed to the emission surface toward a light receiving element; and a light attenuation member for attenuating the received light reaching the light-emitting element from the optical splitter. The optical splitter is formed as an optical surface that includes a fourth optical surface and a fifth optical surface inclined relative to the fourth optical surface. The fourth optical surface is arranged at an angle that allows part of the transmitted light that enters the optical receptacle and reaches the optical splitter to proceed to the second optical surface, and the fifth optical surface is arranged at an angle that allows part of the received light that enters the optical receptacle and reaches the optical splitter to proceed to the third optical surface.

摘要： An optical receptacle having a first optical surface, a second optical surface, a first engaging section, and a second engaging section. The first optical surface has incident thereto first emitted light emitted from a photoelectric conversion element. The second optical surface emits, towards an end surface of an optical transmission body, the first emitted light that has been incident to the first optical surface and has passed through the interior of the optical receptacle. The first engaging section is arranged on a first side surface that is different from the surface on which the first optical surface is formed and the surface on which the second optical surface is formed. The second engaging section is arranged on a second side surface facing the first side surface across an optical path for the first emitted light or a second emitted light.
