The discloser provides a multi-input and multi-output optical switch capable of switching over all WDM wavelengths. An optical switch according to one embodiment includes: an optical demultiplexing element (3) that demultiplexes an optical signal from at least one input port into individual wavelengths; a first optical deflection element (5), which deflects an incident optical signal, that deflects the wavelength-separated optical signal incoming from the optical demultiplexing element to change a traveling direction for each wavelength to a switch axis direction perpendicular to a wavelength dispersion axis direction; a second optical deflection element (8) that deflects the optical signal incoming from the first optical deflection element to change the traveling direction to the switch axis direction for output to at least one of the output ports; and an optical multiplexing element (10) that multiplexes the optical signal with the different wavelengths incoming from the second optical deflection element.

The field plate includes a first portion located between the main surface of the semiconductor substrate and the guard ring electrode, and a second portion located between the main surface of the semiconductor substrate and the channel stopper electrode. The first portion has a portion overlapping with the guard ring electrode when viewed in a plan view. The second portion has a portion overlapping with the channel stopper electrode when viewed in the plan view. In this way, a semiconductor device allowing for stabilized breakdown voltage can be obtained.
Abstract:
The technical problem to be solved is to change the thickness of the colored resin layer of the preform gradually in the upward or downward direction, by utilizing a tendency of gradual decrease in the thickness of the colored resin layer caused by the flow of the main resin inside the preform mold when the main resin and the colored resin are injected into the mold. This involves adjusting the injection pattern including the time of starting and ending the supply of the main resin and the colored resin, and pressure or velocity profiles, reducing the thickness of the colored resin layer gradually upstream or downstream, injection-molding the preform in which a color-gradated portion associated with the thickness of the colored resin layer has been formed, and biaxially drawing and blow molding this preform into a bottle having a color-gradated portion.

In one surface of a semiconductor substrate, an n− layer, a p base layer, a p well layer, another p well layer, a channel stopper layer, an emitter electrode, a guard ring electrode, and a channel stopper electrode for example are formed. In the other surface of the semiconductor substrate, an n+ buffer layer, a p+ collector layer, and a collector electrode are formed. In a curved corner of the p well layer, a p low-concentration layer having a lower impurity concentration than the impurity concentration of the p well layer is formed from the surface to a predetermined depth.
