Abstract

A highly birefringent polymer photonic crystal fiber (PCF) for polarization maintaining is investigated in this work. A triangular structure of circular air holes included in polytherimide polymer (PEI) with a defected core for high birefringence is modeled. The properties of this structure are simulated with a full vector finite element method (FVFEM) using PML (Perfect Matched Layer) as boundary condition. The optimized design ensures a very high birefringence of 4.9 10⁻² at a wavelength of 1550nm. Furthermore, we have achieved an extremely low confinement loss around 10⁻⁶dB/km and negative chromatic dispersion of 180ps/(nm.km) along the y polarization at the operating wavelength. Owing to the excellent polarization maintaining properties, the proposed fiber design could be easily suitable for optical sensor applications. The proposed structure could also enhance the dispersion compensating devices in high bite rate transmission network.
