Abstract

The optimum parameters' expressions of the lens duct are theoretically deduced with the help of numerical analysis of ray tracing. Based on the theoretical analysis, we simulated the rays' transmission trace in the duct and calculated the intensity distribution of the output beam. The influence of the parameter's value on coupling efficiency is also analyzed in the paper. With the optimum parameters lens duct, we implemented the coupling experiment. A smooth and symmetric beam with high quality is obtained. The coupling efficiency of the lens duct is larger than 91%. The experimental results agree well with the theoretical analysis. More important, the duct's coupling efficiency is better than the results reported previously.
