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.
