摘要：In this research work an analysis has been carried out on symmetric dual core hexagonal PCF-based polarization beam splitter by using finite element method (FEM). The splitter designs are carried out with hexagonal PCFs with simple symmetric design by varying only air holes diameter. The results of numerical calculation show that coupling lengths are higher for polarization splitters with larger air hole diameters and with the increase of operating wavelength coupling length decreases. Furthermore it is possible to obtain an 8.4 mm-long polarization beam splitter with high extinction ratio (250dB). This study will be very helpful to design and manufacture simple PCF based splitters with better performance.
