This paper presents the design of an index guided highly birefringentphotonic crystal fiber which promises to yield very large birefringence ~3.33 X10^(-2) at 1550 nm and ~1.75 X 10^(-2) at 1064 nm as well as large effectivenonlinearity ~80 W^(-1)km^(-1). Optical supercontinuum generation in theproposed fiber using a 1064 nm pump source with peak power of 1kW has been alsopresented. Finite difference time domain method (FDTD) has been employed toexamine the optical properties such as fiber birefringence, mode field,V-parameter, walk-off and optical nonlinearity, while the Split-step Fouriermethod is used to solve the nonlinear Schrodinger equation felicitating thestudy of supercontinuum generation. Simulation results indicate that horizontalinput pulse yields superior continuum in comparison to that of the verticallypolarized input. However, the broadening of the continuum is about 1450 nm incase of horizontally polarized input light whereas it is approximately 2350 nmfor vertically polarized.
