发明名称 Optical receptacle and optical module including the same
摘要 An optical receptacle includes a cylindrical optical fiber attaching section for attaching an end portion of an optical fiber by insertion; a cylindrical photoelectric conversion device attaching section that includes an inner circumferential surface into which a photoelectric conversion device having a light-receiving element is inserted and for attaching the photoelectric conversion device with an adhesive that is interposed within an annular adhesion space; and a lens for optically coupling the end portion of the optical fiber and the light-emitting element, and the lens is a Fresnel lens in which a second face that faces the light-receiving element includes a convex face.

主权项 1. An optical receptacle comprising: a cylindrical optical fiber attaching section for attaching an end portion of an optical fiber by insertion; a cylindrical photoelectric conversion device attaching section that includes an inner circumferential surface into which a photoelectric conversion device having a light-receiving element is inserted and for attaching the photoelectric conversion device with an adhesive that is interposed within an annular adhesion space; and a lens for optically coupling the end portion of the optical fiber and the light-emitting element, wherein the lens is a Fresnel lens in which a second face that faces the light-receiving element includes a convex face, wherein: the Fresnel lens is formed such that a focal point is shorter and an axial length of the adhesion space is longer compared to a convex lens having the same optical power.
