Design and Evaluation of Immersed Wideband Non-polarizing Beam Splitter Using ZEMAX Pro-gram and Needle/ Tunneling Method [ ]

Herein a wideband non-polarizing cube beams splitters (NPBSs) for the telecommunication C-band. We engage analy-sis/simulation and design/optimization methods, using an optical design software ZEMAX-EE and Needle/Tunneling synthesis method to find optimal beam splitter parameters. Similar design parameters of minimum layers with ternary dielectric materials were introduced. The results show that ZEMAX software has the ability to design thin film non-polarizing beam splitters and in comparison to needle/tunneling method has reasonable result. Moreover, NPBSs are provided exhibiting ~ 50/50 beam ratio with reasonably tolerant deviations in angle of incidence.
