Abstract: PROBLEM TO BE SOLVED: To obtain high single mode yield, and to reduce fluctuation of an oscillation threshold current and light emission efficiency by setting the absolute value of a gain connection coefficient near a region where reflection other than the distribution feedback of a laser beam is generated smaller than that in other regions. SOLUTION: In a laser element, diffraction grating is not formed in a region from each of end surfaces S1 and S2 of a resonator to length L1 and L2, and a diffraction grating 9 is formed merely at a part with length (L-L1-L2) at a center. More specifically, the region from the end surfaces S1 and S2 of the resonator to length L1 and L2 is set to an upper cladding layer 6 itself, thus preventing gain connection at this part, and hence setting the regions L1 and L2 to a region where the absolute value of a gain connection coefficient is smaller than a region where the diffraction grating 9 is positioned. Then, in the laser element, the diffraction grating does not exist near the end faces S1 and S2 of the resonator, thus preventing the gain connection of a standing wave caused by distribution feedback, and hence reducing the fluctuation of laser characteristics.
