Abstract:A polarization-insensitive four-port beam splitter based on the plus-shaped ridge structure is introduced. The ridge of this grating is a plus-shaped resin material. Based on the rigorous coupled-wave analysis and the simulated annealing algorithm, the transmission efficiency of the zeroth order under TE polarization is 1.79%, and the efficiencies of 22.21%/22.19% for the ± first/± second orders are diffracted. Meanwhile, the transmission efficiency of the zeroth order under TM polarization is 0.13%, and the e… Show more
