Abstract

The invention relates to a coupling method and system for a laser. The coupling method for the laser comprises the following steps: determining a to-be-coupled position of a collimating lens (14), so that light emitted from a light-emitting chip (12) is collimated into parallel light through the collimating lens (14); and based on an active optical coupling method, determining a to-be-coupled position of the first converging lens (16), so that the parallel light is converged at a predetermined position inside the tube shell (11) through the first converging lens (16), and at the predetermined position, the converged light can be coupled with the tube core of the optical fiber. According to the coupling method and system of the laser, coupling of optical devices is achieved through an active coupling method, and the coupling efficiency of the laser is remarkably improved.

Description

technical field [0001] Embodiments of the present disclosure relate generally to the field of optical communications, and more particularly to coupling methods and systems for lasers. Background technique [0002] Some optical communication devices of optical communication systems include semiconductor lasers (eg, laser diode chips) as light sources. Lasers are widely used in sensing and analog modulation, and coupling efficiency has always been one of the indicators that laser products are very concerned about. Improving coupling efficiency plays a crucial role in improving product performance. In the actual production process The actual coupling efficiency is often quite different from the theoretical value. Conventional laser coupling methods are unsatisfactory, and it is expected that the coupling efficiency of lasers can be improved. SUMMARY OF THE INVENTION [0003] Embodiments of the present disclosure provide a coupling method and system for a laser aimed at addr...
