Paper Abstract

In this paper, a novel micro pseudo-spherical lens is proposed to resolve the intrinsic high insertion loss problem associated with the micro spherical lens, and yet retain its other good qualities. The design parameters for this micro pseudo-spherical lens are optimized using Gaussian beam matrix propagation method. A geometric ray-tracing program is also used to calculate the coupling efficiency for collimator pairs. The simulation results for all four different types of micro lenses (pseudo-spherical, spherical, aspheric and GRIN lenses) are presented and compared to experimental results. It is shown that the novel micro pseudo-spherical lens presents significant performance improvement over the micro spherical lens, and offer similar performance to GRIN and micro aspheric lenses.
