Polarization Properties of High-Birefringence Polymer Photonic Crystal Fiber

This fiber will have important applications in the fields of polarization maintaining transmission system and dispersion compensation. We propose a new type of polymer photonic crystal fiber and numerically investigate its birefringence and dispersion. Based on the full-vector finite element method, it is shown that the proposed structure provides high birefringence and negative dispersion. Numerical results show that the birefringence of the polymer PCF reaches 10^-2. Dispersion and its slope are also negative over the C band.This fiber will have important applications in the fields of polarization maintaining transmission system and dispersion compensation.
