摘要： A semiconductor device includes a semiconductor substrate, a lower electrode, a magnetoresistive element, an upper electrode, and a protective film. The lower electrode is formed over the semiconductor substrate. The magnetoresistive element includes a fixed layer, a tunneling insulating film, and a free layer. The upper electrode is disposed over the free layer. The protective film covers the sides intersecting the main surfaces of the lower electrode, the fixed layer, the tunneling insulating film, the free layer, and the upper electrode. The fixed layer, whose magnetization direction is fixed, is disposed over the lower electrode. The tunneling insulating film is disposed over the fixed layer. The free layer, whose magnetization direction is variable, is disposed over a main surface of the tunneling insulating film. The width of the upper electrode is smaller than that of each of the lower electrode and the fixed layer.

摘要： The present invention relates to an optical receiver, in which the transmittance of a Mach-Zehnder interferometer can be locked at a normal operation point in a simple structure and control.A transmittance detecting circuit and a minute modulation signal detecting circuit are provided in parallel after a balanced optical receiver, and a switch is selectively connectable either a minute modulation signal detecting circuit and a transmittance detecting circuit. In the initial stage of frequency pull-in, the switch is set to connect the transmittance detecting circuit to the synchronous detection circuit. If the transmittance detecting circuit detects that the transmittance of the Mach-Zehnder interferometer at the carrier frequency becomes a desired transmittance, the connection of the switch is switched from the transmittance detecting circuit to the minute modulation signal detecting circuit.
