ABSTRACT:
Disclosed is a frequency stabilized light source including a semiconductor laser chip and a finite Fourier diffraction grating with a corrugated profile with a continuous first order differential coefficient. The laser chip emits the output light from its one facet into the diffraction grating with the diffracted light from the grating being fed back to the laser chip, so that the laser chip emits the output light with a stable wavelength from its another facet. The arrangement produces the output light with high frequency purity and high adjustment accuracy and yet wide frequency tunable range.
