摘要
本文提出了一种实现半导体激光器和多模光纤耦合的实用化方法。用一段直径为600μm的裸石英光纤对半导体激光器的输出光束进行准直整形;用半球端光纤对准直后的光束进行聚焦后直接实现和光纤耦合。研究表明,采用该方法后的耦合效率在80.0%左右。该耦合系统制作简单,调试和封装方便,且工艺稳定,因而在各种半导体激光器和光纤耦合方面具有广泛的应用前景。
In this paper, a practical method to implement the coupling between a semiconductor laser and a multi-mode fiber is presented. First, the output light beam from a laser diode is collimated by using a section of the optical fiber with a diamter of 600μm. Then, the collimated light beam is coupled to the fiber directly through a sphere fiber end. The research shows that this method has a coupling efficiency of 80.0%. Because of being easy to make, convenient to adjust and package and having a stable process, this coupling system can find wider applications in the coupling of various semiconductor lasers with multi-mode optical fibers.
