Abstract

The emergence angle of specialty solid coupled (SSC) optical taper is numerically studied by using ray-tracing method, which depends on the shape curve function. The relationships between the taper length, shape factor, large-end and small-end radii and the emergence angle are analyzed, respectively. The results show that the variation of small-end radius has great influence on the range of emergence angle for SSC optical taper. Therefore, given the shape curve function of the SSC optical taper, the emergence angle can be used for analyzing the transmission loss of SSC optical taper.
