Technical Examples

A DFB semiconductor laser device includes a diffraction grating extending parallel to a laser cavity. The diffraction grating has ununiform structure wherein some of the corrugation patterns of diffraction grating are omitted periodically, the diffraction grating has different duty ratio between the area near the front facet of the laser cavity and the area near the rear facet, or the length of the diffraction grating is smaller than the cavity length and the width of the diffraction grating reduces in the vicinity of the rear end of the diffraction grating down to zero at the rear end.
