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.

Abstract: A metasurface reflector includes: a first metal layer and a second metal layer stacked in a first direction; and a dielectric layer provided between the first metal layer and the second metal layer in the first direction. The dielectric layer includes a main surface on which the second metal layer is provided. The metasurface reflector is divided into a plurality of unit regions arranged in a second direction along the main surface and in a third direction along the main surface and intersecting the second direction. The second metal layer includes metal units respectively provided in all or some of the plurality of unit regions. Lengths of metal units, which are arranged in the second direction and set for a same wavelength among the metal units, in the second direction are different from each other.

Abstract: In a solar cell in a sheet form, a first cured resin layer, a substrate containing a resin, a photoelectric conversion layer, and a second cured resin layer are stacked in this order. The linear expansion coefficient of the first cured resin layer is not less than that of the second cured resin layer, and the linear expansion coefficient of the second cured resin layer is larger than that of the substrate. When the cure degree of a first surface of the first cured resin layer facing the substrate is C1 % and the cure degree of a second surface of the first cured resin layer is C2 %, C2 is larger than C1 and (C2−C1) is 2 to 15%. A surface on the first cured resin layer of the solar cell is warped convexly and a surface on the second cured resin layer is warped concavely.
