英文摘要PURPOSE:To uniformize carrier distribution in the longitudinal direction of a resonator by a simple single-electrode structure and realize a narrow spectral line width, by making the conductive impurity density of the upper clad layer higher at the end sections of the resonator than at the center section thereof. CONSTITUTION:A clad layer just above an active layer 104 is changed in the axial direction, and the center section where light intensity distribution concentrates makes a high-density clad layer 106, and both end sections of low light intensity distribution make low-density clad layer 105. Namely, the impurity density of the clad layer just above the active layer 104 is changed according to the light intensity distribution in the processing direction of light, and a part where light is strong is made to have a low density and parts where light is weak are made to have a high density. This uniformizes the carrier distribution in the longitudinal direction of a resonator by a simple single- electrode structure, and realizes a narrow spectral line width.
