摘要

为了提高分布式反馈（DFB）激光器与光纤的耦合容差和耦合效率

文章对DFB激光器与单模光纤的耦合特性进行了理论分析

提出了一种激光器与无源光纤的双透镜耦合系统。采用光线追迹软件仿真了该双透镜系统的耦合效率及容差。传统的硅或氮化铝（AlN）光学耦合平台需要集成到激光驱动电路的有机基板上

文章直接采用有机基板作为光学耦合平台

省去了集成到有机基板的步骤

使组装更方便

集成更简单。对该结构进行应力分析

仿真了BT有机材料、AlN陶瓷材料以及FR4的有机材料分别作为基板材料在最高工作温度下产生的翘曲。根据仿真结果制作了此双透镜系统

并进行了测试。测试结果显示该系统的耦合损耗为4.9 dB

表明此结构可为DFB激光器与单模光纤的耦合提供参考依据。

Abstract

In order to improve the coupling tolerance and coupling efficiency of Distributed Feedback（DFB） laser and single mode fiber

the coupling characteristics of DFB laser and single mode fiber are theoretically analyzed. A new dual lens coupling system of DFB laser and passive fiber is proposed. The coupling efficiency and coupling tolerance of the dual lens system are simulated by optical software. The traditional silicon or AlN optical coupling platform also needs to be integrated into the organic substrate with the laser driver circuit

which is not conducive to the integration of the system. This paper directly uses the organic substrate as the optical coupling platform

eliminating the need to re-integrate into the organic substrate

which makes the installation easier and the integration simpler. The stress analysis of the structure was carried out to simulate the warpage of BT organic materials

AlN ceramic materials and FR4 organic materials as substrate materials at the highest working temperature. Based on the simulation results

the dual lens system was fabricated and tested. The test results show that the coupling loss of the system is 4.9 dB

which indicates that this structure can provide reference for the coupling of DFB lasers and single-mode fibers.
