Analysis of the reflective polarizer based on dielectric nanofibers

Numerical calculations were carried out to find the mechanisms of a nanofiber based reflective polarization sheet (RPS) using the finite-difference time-domain (FDTD) method. The simulation showed that the birefringence of nanofiber layers can make a reflective polarizer with small energy loss. In addition, the simulation demonstrated that the diameter of nanofibers and the spacing between them affected the extinction coefficient of RPS depending on its polarization. According to the calculations with various diameters of the nanofiber, there exists an optimum diameter of the nanofibers for maximum extinction coefficient.
