Abstract
A novel photonic crystal fibers (PCFs) based polarization splitter is proposed in this paper. It is designed by highly birefringent dual-core PCFs which hollow ring defects are used in its one direction to break the structural symmetry. Compared to the previous methods achieving high birefringence, this new type of PCFs can partly overcome the design and fabrication limitations for the PCF-based polarization splitter. Its transmission properties, coupling lengths for the two orthogonal polarizations and the performance of the proposed polarization splitter are investigated respectively. The results show that a 0.676-mm-long polarization splitter can be obtained. When the splitting ratio is better than -15dB, its bandwidth is about 45.8nm.
