Abstract: An optical semiconductor element includes: an optical waveguide body; a first electrode that is disposed on a second clad layer; a second electrode that is disposed on the second clad layer on one side of the first electrode in a light guiding direction of the optical waveguide body; a third electrode that is disposed on the second clad layer on the other side of the first electrode in the light guiding direction; and at least one fourth electrode that faces the first electrode, the second electrode, and the third electrode with the optical waveguide body interposed therebetween. The optical waveguide body includes a first separation region that electrically separates a first region under the first electrode from a second region under the second electrode and a second separation region that electrically separates the first region under the first electrode and a third region under the third electrode.

Abstract: 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.
