垂直于有源层的不对称扩展光场结构被应用于1020 nm脊形波导激光二极管，以提高其最大无扭结输出功率并降低输出光束的纵横比。结果，该结构实现了超过 400 mW 的无扭结输出功率和小于 2.5 的纵横比。在 50/spl deg/C 下输出功率为 300 mW 时也获得了良好的可靠性。
The structure of an asymmetrically expanded optical field normal to the active layer was applied to 1020-nm ridge waveguide laser diodes in order to increase their maximum kink-free output power and reduce the aspect ratio of the output beams. As a result, a kink-free output power of more than 400 mW and an aspect ratio of less than 2.5 were achieved by this structure. Good reliability was also obtained at an output power of 300 mW at 50/spl deg/C.
