Abstract: An optical modulator is provided with an optical waveguide including an input-side single-mode waveguide for propagating inputted light at single mode, a multi-mode waveguide for propagating the light propagated from the input-side single-mode waveguide at plural guided modes, and an output-side single-mode waveguide for propagating the light propagated from the multi-mode waveguide at single mode to output the light. A lower electrode layer is disposed below the multi-mode waveguide, and an upper electrode is disposed above the multi-mode waveguide. The upper electrode cooperates with the lower electrode layer to apply an electric field to the multi-mode waveguide. A phase of each of the guided modes propagating through the multi-mode waveguide is modulated by applying an electric field to the multi-mode waveguide, and intensity of the light outputted from the output-side single-mode waveguide is modulated by an interference of the phase-modulated guided modes.

Abstract: A light emitting unit includes a substrate, plural light emitting elements disposed on the substrate, and a lens array disposed above the plural light emitting elements. The lens array includes a base and plural lenses that each focus light emitted from a corresponding light emitting element among the plural light emitting elements. The base includes a boundary surface which is in contact with the plural lenses and an opposing surface which opposes the plural light emitting elements. The distance from one of the plural light emitting elements to the boundary surface of the base which is in contact with a corresponding lens among the plural lenses is different from the distance from another one of the plural light emitting elements to the boundary surface of the base which is in contact with a corresponding lens among the plural lenses.
