Title Researching the micro-ball lens’coupling efficiency based on ZEMAX.
Abstract
Semiconductor lasers and fiber coupling technology has developed into a more mature stage as an important technology. And it has been widely used in optical fiber communication, optical fiber sensing and so on.
This article is based on the beam characteristics of the semiconductor
laser and fiber transmission, the epitome of semiconductor lasers and fiber-coupled way, and the discussion of micro-ball lens characteristics.
Depending on the optical design software, ZEMAX, we analyzed the influence of the distance between the micro-ball lens and the laser on the coupling efficiency, in the condition that the refractive index and dispersion coefficient of the micro-ball lens, and the laser emission of light field parameters are identified. By ZEMAX software’s analysis, we can find out the best position to make here be the maximum coupling efficiency of all the different locations of the distance between the laser source and the ball lens surface.
Keywords Semiconductor lasers, Micro-ball lens, Fiber coupling, ZEMAX, Maximum coupling efficiency.
