Fiber optic parametric amplifiers (FOPA) based on triangular photonic crystal fiber (PCF) is analyzed theoretically. Equations about parametric unsaturated gain and gain bandwidth in normal or abnormal dispersion regimes are derived. Numerical simulations are performed for single-pump and two-pump FOPAs, respectively. Comparisons with FOPAs based on dispersion-shifted fiber (DSF) and highly nonlinear fibers (HNLF) are carried out. The results show that, due to the excellent dispersion profile and nonlinearity of PCF, single-pump FOPA has higher peak gain and two-pump FOPA presents higher flat gain over wider bandwidth.

We propose and design a spiral photonic crystal fiber with elliptical air holes for achieving high birefringence, large nonlinearity, and negative dispersion. The structure is designed using chalcogenide glass (As2S3) for different ellipticity ratios of air holes in the cladding and the effect on various properties is observed. The proposed structure has birefringence of the order 10−2, nonlinearity of 26739.42 W−1 m−1, and dispersion of −1136.69 at 0.85 μm. An accurate numerical approach based on finite element method is used for the design and simulation of the structure. Due to high birefringence and negative dispersion, the proposed structure can be used for polarization control and dispersion compensation, respectively.
