Design and Analysis of Chalcogenide Based Photonic Crystal Fiber for Non-linear Optical Applications

The linear and nonlinear optical properties of the chalcogenide photonic crystal fiber (PCF) is designed and analyzed. Numerical simulation shows that the proposed PCF is highly nonlinear and provides all normal dispersion values in the range of wavelength 2 to 5 μm, The non-linear coefficient of designed PCF is 3.5 W−1m−1 at wavelength 2 μm. The designed highly nonlinear and all normal dispersion chalcogenide PCF can be very useful in nonlinear optical applications such as generation of supercontinuum in the mid-infrared wavelength region.
