Abstract
An optical transmitter provided with a supercontinuum light source 4 which is composed of an optical amplifier 2 made by using a polarization maintaining amplification fiber 1 and a polarization maintaining fiber 3 which has a length of at least a specified value, is connected to the output side of the optical amplifier 2 and emits light having a continuous wave and a stable plane of polarization, a polarization maintaining optical demultiplexer 5 which takes out a light with a desired wavelength from the continuous wave light, and an external modulator 6 which superposes desired information upon the light with the desired wavelength.
