Abstract
Square-lattice microstructure geometry of photonic crystal fibers made with high nonlinearity non-silica glass composition material as well as fused silica glass are studied here for modal propagation, dispersion analysis and supercontinuum generation. Our investigation of nonlinear propagation of low threshold power femtosecond pulse aims at generating supercontinuum in the near and mid infrared region using these highly nonlinear fibers. We performed a series of analyses through varying parameters of square-lattice geometry to map a desired broadband window. We also demonstrate a compact high power broadband source in visible region generated within few centimeter length of the fused silica square-lattice microstructure.
