Abstract
Abstract-In this paper, we presented a design of high nonlinear fiber with novel cladding structure photonic crystal fiber based on pure silica. This structure has arc air-holes with square lattice arrangement in 6 rings. For the model analysis of the photonic crystal fiber structure, we use a fully-vectorial mode solver based on the finite element method. Numerical simulation show that this structure exhibits an extremely high nonlinear coefficient values, which can more than many times larger than that of conventional PCF, and it also show that the optimized structure of the PCF has near-zero flattened dispersion slope at communication wavelength.
