    摘要： An optical fiber array includes an alignment substrate, a plurality of ferrules, and a plurality of optical fibers. The alignment substrate has a plurality of guide holes which are two-dimensionally arrayed and extend through the substrate. The ferrules are respectively inserted into the guide holes in the same direction and have through holes in the central portions. The optical fibers are fitted and held in the respective through holes. The guide hole is formed into a cylindrical shape having a diameter substantially equal to the outer diameter of the ferrule. The light incident/exit end face of the optical fiber is exposed on one end face of the ferrule.

    摘要： Disclosed is a photonic switch that includes a plurality of optical-path switching means having movable light reflecting portions that guide light from each of a plurality of input ports to any output port among a plurality of output ports. Each of the optical-path switching means is made to produce a specific loss so as to reduce path-to-path variations in loss along the paths from the input to the output ports. Specifically, loss along a path is the total of loss based upon optical path length and loss produced by the optical-path switching means. A specific loss is produced by each of the optical-path switching means in such a manner that total loss is equalized from path to path.

    摘要： A concave channel type DMOS structure having an improved gate-to-source breakdown voltage are disclosed. By establishing a curvature at a corner portion of a lattice-like pattern in a groove portion for forming the concave channel structure, the shape of the tip of a three-dimensionally projecting portion of a semiconductor region determined by a plane angle of the corner portion in the lattice-like pattern and an inclination of the groove portion is rounded. That is, a three-dimensionally sharpened corner portion in the concave channel structure is rounded, and thereby electric field concentration at the corner portion is suppressed.
