Abstract: An aspect of the present invention is an optical modulator, comprising a waveguide substrate and a multiplexing optical system. The waveguide substrate includes a first modulation portion, a second modulation, a first optical path and a second optical path. The multiplexing optical system includes a first surface and a second surface. First output light output from the first optical path and second output light output from the second optical path are input from the first surface and are output after there are combined at a combining point of the second surface. An optical path length between the first surface and the combining point in the first output light is larger than that of in the second output light. An optical path length between the first modulation portion and the first surface and an optical path length between the second modulation portion and the first surface are different.

Abstract: An aspect of the present invention is an optical element that combines light waves using a spatial optical system, including a housing section, an optical waveguide element, a combine section, and a collimator section is provided. The housing section has a storage space and is formed by joining two or more members together. The optical waveguide element is provided in the storage space and emits at least two light waves. The combine section is provided outside the storage space and combines the light waves emitted from the optical waveguide element outside the housing section using a spatial optical system. The collimator section is connected to the housing section, holds the combine section, and includes a light focusing section configured to focus a light wave combined by the combine section and an optical fiber to which the light wave focused by the light focusing section is introduced.
