Abstract: PROBLEM TO BE SOLVED: To provide a dispersed phase shift structure distributed feedback semiconductor laser (DFB-LD) which operates stably in a single mode, is high in slope efficiency, and has a large production tolerance. SOLUTION: This distributed feedback semiconductor laser carrying out optical feedback by a diffraction grating is equipped with an element which is divided into three regions 1, 2, and 3 in the lengthwise direction.

With this setup, an internal electric field is dispersed to phase shifts at two spots, the phase shifts reside on the forward side, and light intensity concentrates in the forward side with asymmetrical distribution, so that front end face slope efficiency is improved.  A distance between two phase shift spots is kept constant independently of a positional deviation that occurs when the element is cleaved, so that the characteristics of an element have a large tolerance for the deviation of a cleavage position, and a DFB-LD operating stably in a single mode and high in slope efficiency can be realized with high yield.
