文摘

In this paper, a novel design of an ultra-compact polarization splitter based on soft glass photonic crystal fiber with a central chalcogenide glass rod is reported and analyzed. In order to enhance the birefringence between even and odd modes for the proposed design, large cladding air holes are infiltrated by nematic liquid crystal material. The numerical results show that the reported splitter has a short device length of 111.244 μm with bandwidths of 76 and 88 nm and crosstalk of −50 and −55 dB for x and y-polarization modes, respectively at wavelength of 1.55 μm. Therefore, the suggested polarization splitter has advantages in terms of compactness, large bandwidth and low crosstalk for the two polarization states.
