Abstract: | We propose a novel method to achieve highly nonlinear photonic crystal fiber (PCF) by filling highly nonlinear liquid chloroform in the core of hollow-core PCF (HCPCF). The dispersion properties and electric field distribution of the fundamental mode are calculated by using the full-vector finite element method (FVFEM). Simulation results indicate that the zero-dispersion wavelength (ZDWL) of the chloroform-filled PCF is adjustable around 800 nm. Hence the femtosecond laser pulses with central wavelength at 800 nm can propagate in anomalous dispersion regime of the PCF, inducing the spectra broadening. |
