Abstract: A magnetoresistive effect device includes at least one magnetoresistive effect element including a magnetization fixed layer, a spacer layer, and a magnetization free layer, a first port, a second port, a first signal line which is connected to the first port and through which high-frequency current corresponding to a high-frequency signal input into the first port flows, a second signal line, and a direct-current input terminal. The magnetoresistive effect element is arranged so that a high-frequency magnetic field occurring from the first signal line is applied to the magnetization free layer. The magnetoresistive effect element is connected to the second port via the second signal line. The direct-current input terminal is connected to the magnetoresistive effect element.

Abstract: In a variable voltage circuit 50, a resistive element 104 and a magnetoresistance effect element 108 are connected in series between a first voltage source 101 and a second voltage source 102. A magnetic field supply mechanism 121 that applies a magnetic field to the magnetoresistance effect element 108 is provided in the vicinity of the magnetoresistance effect element 108. The magnetic field supply mechanism 121 can vary the resistance value of the magnetoresistance effect element 108 by varying the magnetic field. A node 106 between the resistive element 104 and the magnetoresistance effect element 108 is connected to an output terminal 103.

Abstract: This optical waveguide detection element includes a substrate, an optical waveguide layer formed on the substrate, and a photodetector. The optical waveguide layer includes a first optical waveguide in which visible light having a wavelength of 380 nm to 800 nm propagates, a second optical waveguide in which near-infrared light having a wavelength of 801 nm to 2000 nm propagates, and a third optical waveguide in which light propagates to a light receiving surface of the photodetector. A visible light output port of the first optical waveguide from which the visible light is output, a near-infrared light output port of the second optical waveguide from which the near-infrared light is output, and a reflected light input port of the third optical waveguide to which the near-infrared light is reflected and returned are arranged on one end surface of the optical waveguide layer.
