本文介绍了一种具有集成多模干涉耦合器的新锥形半导体激光器。新激光器的种子来源是多模干扰耦合器半导体激光器，它克服了脊方波导区域中单模式输出与增益中等体积之间关系所带来的局限性。The simulation results show that the multi-mode interference coupler can effectively provide a spatial single- mode seed light source for the tapered output waveguide, and the tapered output waveguide of the tapered semiconductor laser can also effectively reduce the optical power density of the output laser, which verifies the feasibility of the design scheme and provides a new idea for the design of high beam quality and high power tapered半导体激光器。
