Design and Analysis of Polarization Maintaining Ultrahigh Birefringent, Dispersion Flattened Photonic Crystal Fiber Having Low Confinement Loss

Design and analysis of ultrahigh birefringent photonic crystal fiber having low confinement loss and nearly zero dispersion characteristics has been presented. The suggested design has phosphate glass rectangular slab surrounded by rectangular array of four air holes in core region and circular air holes in the cladding region. Photonic crystal fiber structure is designed, simulated and analyzed by using opti FDTD simulation software. The proposed design shows ultrahigh birefringence (~0.023) and low confinement loss at 1.55μm. Such high value of birefringence eliminates fluctuation in polarization state.
