摘要： A semiconductor module may include a plurality of semiconductor elements; and a first power terminal, a second power terminal and a third power terminal electrically connected to the plurality of semiconductor elements. The plurality of semiconductor elements may include at least one upper arm switching element electrically connected between the first power terminal and the second power terminal; and at least one lower arm switching element electrically connected between the second power terminal and the third power terminal. A number of the at least one upper arm switching element may be different from a number of the at least one lower arm switching element.

摘要： A phase shifter includes a substrate, waveguides and a wiring portion. The substrate includes optical waveguide regions and contact regions. Each contact region has contact portions. The waveguides are disposed at the substrate, and each of the waveguides accumulates carriers to modulate a phase of light for guiding propagation of the light. The wiring portion electrically connects each of the waveguides and each of the contact portions. Each of the contact portions connecting each of the waveguides to a corresponding one of electrodes to inject the carriers into each of the waveguides. Each of the waveguides has a lengthwise direction defined as a first direction, and a direction that is perpendicular to the first direction and is parallel to a surface of the substrate is defined as a second direction. The optical waveguide regions and the contact regions are disposed to be alternately aligned along the second direction.
