ABSTRACT:
An optical transmitter comprises an optical transmission unit having a semiconductor optical amplifier, and an optical connector having a plurality of diffraction gratings. The plurality of diffraction gratings are arranged in parallel with each other and partly reflect respective wavelengths of light different from each other. The optical connector is connected to the optical transmission unit such that light from the semiconductor optical amplifier is incident on one of the plurality of diffraction gratings.
