稳定耦合效率的沟槽结构半导体激光器
Stable Coupling Efficiency of Semiconductor Lasers with Groove Structure
摘要
Abstract
In order to stabilize the coupling efficiency of the laser beam from the semiconductor laser through optical fiber,a laser with groove structure was proposed,and the laser beam,coupling efficiency and P-I characteristics were researched.The periodic grooves in the ridge region of the laser were etched to improve the gain distribution in the active region of the laser.The laser beams of the common laser and the groove structure laser were analyzed,the coupling efficiency and P-I characteristics were tested.The results show that the strip laser with groove structure can stabilize the cavity mode,avoid the "Kink" effect and improve the coupling efficiency to 97.7％.The laser with groove structure can solve the phenomenon of optical filaments fluctuation effectively and improve the stability coupling efficiency of the beam.关键词
