Abstract

We propose a new polarization splitter (PS) based on Ti and liquid infiltrated photonic crystal fiber (PCF) with high birefringence. Impacts of parameters such as shape and size of the air holes in the cladding and filling material are investigated by using a vector beam propagation method. The results indicate that the PS offers an ultra-short length of 83.9 μm, a high extinction ratio of -44.05 dB and a coupling loss of 0.0068 dB and at 1.55 μm. Moreover, an extinction ratio higher than -10 dB is achieved a bandwidth of 32.1 nm.
