Abstract
A wavelength tunable laser which includes a first mirror, a diffraction grating to diffract a laser beam into a plurality of diffracted laser beams, at least one feedback waveguide, at least one second mirror. Each feedback waveguide precedes one of the second mirrors, and a phase detector to detect an error in a wavelength of a received laser beam with respect to a desired wavelength.
