Abstract
An optical transmitter includes: a plurality of laser diodes each of which outputs signal light having a wavelength that is different from a wavelength of other signal light; an optical multiplexer that is disposed adjacently to the laser diodes along a first direction, and that multiplexes the signal light output from the respective laser diodes; and a driving circuit that is disposed adjacently to the optical multiplexer along a second direction that is different from the first direction, and that drives the laser diodes. The optical multiplexer and the driving circuit are integrated.
