Abstract
An 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 a first to a 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 a first axis intersecting the first end surface. The third end surface is oblique with respect to the first axis at an angle greater than zero degrees and less than 90 degrees. The optical fibers extend in the supporting block and is exposed to the third end surface. The reflecting plate is provided on the third end surface via the intermediate layer. Light from the optical fiber passes through the third end surface which has some roughness, and is reflected by a surface of the reflecting plate.
