    摘要: A light-detecting device includes a base, a first absorption layer, a second absorption layer and a first semiconductor layer. The first absorption layer is located on the base and has a first band gap. The second absorption layer is located between the first absorption layer and the base and has a second band gap and a first dopant. The first semiconductor layer is located between the first absorption layer and the second absorption layer and has a third band gap. The second band gap is equal to or greater than the first band gap, and a third band gap greater than the first band gap and the second band gap. The first absorption layer does not include the first dopant.

    摘要: In a light receiving element, a first semiconductor layer that is formed on the upper surface of a substrate and is formed with a semiconductor of a first conductivity type, a light absorbing layer formed with a semiconductor, a second semiconductor layer formed with a semiconductor of a second conductivity type, a first electrode that is formed in contact with the second semiconductor layer, is formed with a metal, and functions as a reflective film, and a second electrode formed on the first semiconductor layer are formed in a vertical direction on the upper surface of the substrate. In the light receiving element, a slope that is neither perpendicular nor parallel to the substrate plane is formed on the substrate, and incident light that has perpendicularly entered the slope is made to enter the light absorbing layer obliquely with respect to the vertical direction.

    摘要: A photodetector includes a first conduction-type semiconductor layer, a semiconductor light absorption layer provided on the first conduction-type semiconductor layer, and a second conduction-type semiconductor layer provided on the semiconductor light absorption layer. Inside the semiconductor light absorption layer, finely modified portions forming a localized inhomogeneous electric field inside the semiconductor light absorption layer by scattering incident light are provided in a manner of being separated from the second conduction-type semiconductor layer.

    摘要: The light detector includes: a substrate including at least one light receiving area and a light incident surface on which light is incident; and a meta-lens formed on the light incident surface of the substrate to focus the light incident on the light incident surface. When viewed from the thickness direction (Z-axis direction) of the substrate, the meta-lens is formed so as to overlap both an adjacent region adjacent to the light receiving area and a peripheral region that is continuous with the adjacent region and is a region inside the light receiving area along the outer edge of the light receiving area. When viewed from the Z-axis direction, a non-forming region in which the meta-lens is not formed is provided in a region overlapping a central region of the light receiving area in the light incident surface.
