Abstract

Laser radiation coupling into a single-mode optical fiber was numerically simulated. Various options for matching the source of laser radiation with the optical fiber are considered, including direct coupling, insertion of a microlens at the end face of the optical fiber, and adding a lens between the radiation source and the optical fiber. Optimal parameters of matching elements for coupling the radiation of an edge-emitting laser diode and a vertically emitting laser into a single-mode optical fiber are determined, making it possible to obtain calculated coupling efficiencies of 65% and 100%, respectively.
