摘要

We propose a new design of a Photonic Crystal Fiber (PCF) with high negative chromatic dispersion for compensation purpose. The proposed PCF has a hexagonal holey structure with seven air-holes rings with different diameters. For the numerical analyses a scalar finite element method was utilized. This scalar approximation describes the general behavior of the optical propagation in the PCF and yields good numerical results for the exploratory phase of new PCF designs. However, more accurate results would require a vectorial approach. For this new PCF design, values as large as D ≈ - 5000 psm/km were reached at 1.55 μm wavelength.
