摘　　要：模式失配是造成异质光电器件耦合损耗的主要因素。针对异质光电器件耦合模式失配等问题,基于半导体激光器出射光的传输特性以及光子晶体光纤传输模式特性,结合模式匹配原理,对光学透镜进行设计,对半导体激光器出射光进行整形修饰,使其与光子晶体光纤实现模式匹配。此外,利用模式重叠积分分析方法对半导体激光器与光子晶体光纤耦合系统的耦合效率、对准精度要求以及3 dB失配容差进行了研究分析。研究结果表明,半导体激光器出射光经过光学透镜整形修饰之后,可以与光子晶体光纤模式实现高度匹配,能够达到91%的耦合效率且3 dB对准容差为0.5μm。Mode mismatch is a primary factor contributing to coupling loss in heterogeneous optoelectronic devices. In this paper, the transmission characteristics of the semiconductor laser and the photonic crystal fiber are researched. Besides, optical lens are designed to achieve the shaping and modification of the output light of the semiconductor laser. In addition, the coupling efficiency, alignment accuracy requirements and 3 dB mismatch tolerance of the semiconductor laser and photonic crystal fiber coupling system are analyzed by using mode overlap integration. The research results show that the semiconductor laser can be highly matched with the photonic crystal fiber mode after optical lens shaping and modification, and coupling efficiency and 3 dB alignment tolerance can achieve 91% and 0.5 μm, respectively.
