Abstract

An ultrahigh-birefringent nonlinear photonic crystal fiber (PCF) that exhibits low losses and small effective mode area across a wide wavelength range has been presented. The effects of angular orientation on bending losses of the proposed PCFs have been thoroughly investigated by employing a full vectorial finite-element method (FEM). It has been demonstrated that it is possible to design a bending-insensitive nonlinear PCF with a birefringence 9times10^-3 at a 1.55-mum wavelength. Significant improvements on key propagation characteristics of the proposed PCFs have been demonstrated by carefully altering the desired air hole diameters and the hole-to-hole spacing.
