摘要
根据半导体激光器和单模光纤模场分布特点,用模式耦合理论研究了单模光纤与半导体激光器的耦合,结果表明将光纤端面制作成楔形微透镜可以使光纤与半导体激光器的耦合满足模场匹配和相位匹配的要求。用遗传算法对楔形光纤微透镜参数进行优化,得到楔角为88°,柱透镜半径为3.44 μm,耦合距离为6.13 μm时耦合效率达到最佳值,用Zemax光学仿真软件对耦合模型进行仿真,得到耦合效率为88.9%,耦合好的模块经激光点焊及高低温环境测试后,得到最大耦合效率为81.36%。实验结果与仿真结果相差不大,耦合输出功率满足了作为光纤激光器种子源的功率要求。
Abstract
According to the mode field distribution characteristics of semiconductor lasers and single mode fiber, the coupling of the single mode fiber and semiconductor laser is studied by the mode coupling theory, the results show that the fiber end face into a wedge micro lens can make the coupling of fiber and semiconductor laser meet the requirement of the mode field matching and phase matching. Micro lens parameters of wedge type fiber are optimized using the genetic algorithm, the result is that the coupling efficiency achieves the optimum value with wedge-angle of 88°, cylinder lens radius of 3.44 μm and coupling distance of 6.13 μm, the coupling efficiency reaches 88.9% when using the Zemax optical simulation software to simulate the coupling model, the maximum coupling efficiency is 81.36% after laser spot welding and the high and low temperature environment test. The experimental results are similar to the simulation results, the output coupling power can satisfy the demands of seed source power for fiber laser.
