Abstract: An optical module includes a substrate on which an optical waveguide is provided; a housing that houses the substrate and includes a through path arranged on a side wall of the housing so as to extend in a direction that crosses the optical waveguide; a ferrule that houses an end portion of an optical fiber; and an optical path conversion element that is fixed on the ferrule, that is fixed on an end surface of the substrate on the end portion side of the optical waveguide, and that has a size smaller than a width of the substrate and a width of the ferrule along a longitudinal direction of the substrate. The end portion of the optical waveguide is arranged at a position close to the through path of the housing relative to a central portion in a width direction of the substrate.

Abstract: An optical modulator in which an optical signal is input from one side of a package, includes in the package, a chip that optically modulates the optical signal and in which an input waveguide and an output waveguide of the optical signal are led to mutually different destinations each being one end of the chip facing the one side of the package and a side surface of the chip orthogonal to the one end of the chip; an input optical system coupled to the input waveguide of the chip; and an output optical system coupled to the output waveguide of the chip.
