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.

The component comprises: a first filter reflecting first light having a first wavelength and being transparent to second light having a second wavelength and third light having a third wavelength; a second filter reflecting second light and being transparent to third light; and a base transparent to second light and third light. The first filter and the second filter are provided on opposed surfaces of the base. The plastic body has first, second, and third surfaces, and the first surface provides first, second, and third 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 through the first filter and light from the second lens is connected to the path through the second filter. The third surface is a reflecting surface for connecting light from the third lens to the path.

摘要： An optical connecting member realizes an optical connecting between a multi-core fiber and a plurality of single-core fibers by a waveguide part which connects a first end face and a second end face. With the optical connecting member, a connected end which is connected to the first end face is a straight-line portion that is orthogonal to the first end face in each of the plurality of waveguide parts. In addition, a diverged end which is diverged to the second end face is a straight-line portion that is orthogonal to the second end face. Consequently, light that has passed through the waveguide parts is emitted from the first end face and the second end face substantially perpendicularly to the faces, thereby enabling optical connecting loss to be favorably inhibited.
