| abstract |
[PROBLEMS] To increase the stability of the polarization direction without increasing the cost and to make the sectional shape of the output light substantially circular. A resonator structure including an active layer and a plurality of semiconductor layers including a lower semiconductor DBR103 and an upper semiconductor DBR107 provided so as to sandwich the resonator structure are stacked on an inclined substrate. The shape of the current passage region 108b in the oxidized constriction structure is symmetric with respect to an axis parallel to the X axis and passing through the center of the current passage region 108b, and parallel to the Y axis and passes through the center of the current passage region 108b. It is also symmetric about the axis. In addition, in the oxide layer 108a surrounding the current passing region 108b, the thickness of the portion where the oxidation has progressed in the -Y direction is thicker than the thickness of the portion where the oxidation has progressed in the + X direction and the -X direction. Furthermore, the opening width in the X-axis direction of the light emitting portion 115 is smaller than the opening width in the Y-axis direction. [Selection] Figure 3 |
