摘要：
A distributed feedback semiconductor laser, in which the periodic corrugations in the first region and the second region of the light emitting region of the DFB laser have different lengths or depths to make the intensities of the Bragg reflection of the first region and the second region different from each other, thereby obtaining asymmetrical light outputs from the both sides of the DFB laser.
