摘要： An optical receptacle includes an optical receptacle main body and a cylindrical fixing member. The optical receptacle main body includes a first optical surface, a second optical surface, and an annular groove disposed to surround a first central axis of the first optical surface or disposed to surround a second central axis of the second optical surface. The fixing member is configured with a material with a smaller linear expansion coefficient than that of the optical receptacle main body, and is fit to the groove so as to be in contact with at least a part of an inner surface of the groove.

摘要： This optical receptacle comprises: a first optical surface on which light emitted from a VCSEL is incident; a first reflection part which reflects, as monitor light traveling to a detection element; a light separation part which separates monitor light and signal light; a second optical surface which emits the signal light to the end surface of the optical transmission body; and a third optical surface which emits the monitor light reflected by the first reflection part and the monitor light separated by the light separation part to the detection element. Two second reflection parts of the light separation part are disposed so as to be located within a luminous flux of the light incident on the first optical surface such that a predetermined condition is satisfied.

摘要： An electromagnetic flux controlling member includes an incidence surface for allowing incidence of an electromagnetic wave, and an emission surface for emitting the electromagnetic wave incident on the incidence surface to an outside. At least one of the incidence surface and the emission surface includes a base curved surface and a plurality of protrusions arranged on the base curved surface. Each of the plurality of protrusions includes a conical tip portion disposed such that at least a part of an edge of a bottom surface of the conical tip portion makes contact with the base curved surface, and a partially columnar leg portion disposed between the conical tip portion and the base curved surface. A central axis of the conical tip portion and a central axis of the partially columnar leg portion are parallel to a main axis of the electromagnetic flux controlling member.
