摘要： An optical combiner (10) in which fewer parts are used comprises an optical component (12) and a plastic body (14). The component comprises: a first filter (12b) reflecting first light (L1) having a first wavelength and being transparent to second light (L2) having a second wavelength and third light (L3) having a third wavelength; a second filter (12c) reflecting second light (L2) and being transparent to third light (L3); and a base (12a) transparent to second light (L2) and third light (L3). The first filter (12b) and the second filter (12c) are provided on opposed surfaces of the base (12a). The plastic body (14) has first, second, and third surfaces (14a,b,c), and the first surface provides first (16a), second (16b), and third (16c) lenses. The component is provided in the plastic body such that light from the first lens is connected to a path to the second surface (14b) through the first filter and light from the second lens is connected to the path through the second filter. The third surface (14c) is a reflecting surface for connecting light from the third lens to the path.

摘要： A ferrule 10 includes a plurality of holding holes 16, a light incidence/emission plane 21 to pass light entering or emitted from optical fibers F2 respectively held at the plurality of holding holes 16, a plurality of lenses 31 disposed on an optical axes between the respective plural holding holes 16 and the light incidence/emission plane 21, and two or more guide portions to determine a relative position with a ferrule 10 on the other side. A second optical axis L2 between the light incidence/emission plane 21 and the ferrule 10 on the other side is inclined relative to a Z direction. A positional relation between the two or more guide portions is 180-degree rotationally symmetric around a reference axial line extending in the Z direction. A plurality of lenses 31 is disposed disproportionately in a direction opposite to an inclination direction of the second optical axis L2 from a position line-symmetric relative to a straight line crossing with the reference axial line and parallel to an X direction.

摘要： An optical combiner in which the number of parts used is lessened is made of a resin. The optical component comprises a first surface, a diffraction grating, and a second surface. The first surface is a surface providing first, second, and third lenses. The diffraction grating diffracts to a common optical path leading to the second surface light of the first wavelength incident on the first lens, light of the second wavelength incident on the second lens, and light of the third wavelength incident on the third lens. The second surface emits light incident thereon through the common optical path. The optical path from the first surface to the diffraction grating and the common optical path are constituted of the resin.
