Abstract:
An optical processing device includes a semiconductor optical device, and an optical device provided on the semiconductor optical device. The optical device includes one or more optical fibers and a holder having a supporting block, a reflecting plate, and an intermediate layer. The supporting block has first to third end surfaces at one end. The first end surface extends from a bottom surface of the holder to claddings of the optical fibers. The second end surface extends along an axis intersecting the first end surface. The third end surface is oblique with respect to the axis at an angle greater than zero degrees and less than 90 degrees. The optical fibers have facets exposed at the third end surface. The intermediate layer embeds roughness in the exposed facets. It has a refractive index comparable to that of the claddings of the optical fibers.
