Title: Supercontinuum generation in low dispersion and highly nonlinear hexagonal photonic crystal fibers
Abstract: We design a solid hexagonal photonic crystal fiber (PCF) with air holes of different diameters in the cladding region using the finite element method. We achieve a low group velocity dispersion of −5.483 ps2/km and a high nonlinearity of 111.4 W−1 km−1 at 450 nm with d1/Λ being 0.345, which could ensure single-mode propagation. The low dispersion and high nonlinearity form the crucial requirements to generate the supercontinuum (SC) pulse. The designed PCF exhibits a broad SC spectrum of bandwidth 600 nm at an operating wavelength of 450 nm which might find a great relevance in optical sensing applications.
