Abstract: A light flux controlling member of the present invention includes: a vortex surface including a plurality of phase control surfaces having a vortex shape around a central axis and radially divided with the central axis at a center, and a plurality of step surfaces each configured to connect end portions of adjacent two phase control surfaces of the plurality of phase control surfaces. Upper sides of the plurality of step surfaces intersect each other at a center portion of the vortex surface. In side view, a curve extending from the center portion toward an outer periphery part of the vortex surface has an inflection point at the center portion of the vortex surface.

Abstract: Provided is a method for manufacturing an optical receptacle with which the occurrence of bending of a guide pin hole can be suppressed. The method for manufacturing an optical receptacle of the present invention includes an injection step of injecting a resin through a resin injection port of a mold into a cavity of the mold, and a solidification step of solidifying the resin in the cavity of the mold. The cavity of the mold has a protruding portion for forming a recessed portion in a main body of an optical receptacle, a pair of pins for forming a pair of guide pin holes in the main body of the optical receptacle, and a pair of pin-retaining portions. In the injection step, the mold during the injection of the resin is in a state in which the pair of pins are respectively disposed on two end sides of the protruding portion, the resin injection port is disposed so that the resin flows from one end side of the pair of pins toward opposing faces of the pins that oppose each other, one of the pin-retaining portions is disposed in contact with a side of a corresponding one of the pins that is opposite to the opposing face thereof, and the other of the pin-retaining portions is disposed in contact with a side of the other of the pins that is opposite to the opposing face thereof.

Abstract: Provided is an optical receptacle (140) having an installation plane (141), an optical plane, and a reference plane (147). An inclination angle of the reference plane (147) with respect to the installation plane (141) is smaller than an inclination angle of the optical plane with respect to the installation plane (141). Then, a first inclination angle θ1 that is the inclination angle of the reference plane (147) with respect to the installation plane (141) and a second inclination angle θ2 that is an inclination angle of the optical plane with respect to the reference plane (147) are measured. Then, the first inclination angle θ1 is added to the second inclination angle θ2 to calculate a third inclination angle θ3 that is the inclination angle of the optical plane with respect to the installation plane (141).

Abstract: To provide an optical component having no wrinkle in an optical path area of an optical surface, an optical component that optically connects a light-emitting element and an optical fiber includes an optical surface arranged in a middle of an optical path of a light emitted from the light-emitting element to the optical fiber to reflect the light. The optical surface includes an optical path area that reflects the light and a non-optical path area other than the optical path area, and the optical path area and the non-optical path area are placed coplanarly. The optical path area has a smooth surface, and at least a part of the non-optical path area has a rough surface rougher than the optical path area.
