| Abstract(in English) | An approximate analytical method for the solutions of nonlinear photonic crystal fibers (PCFs) is newly proposed. Replacing a PCF with a conventional step-index fiber, closed form expressions for the effective refractive index and effective core area of nonlinear PCFs are derived. To define the equivalent cladding index, the effective index of the so-called fundamental space-filling mode, which is calculated from the empirical relation for the effective normalized frequency, is introduced, and thus, nonlinear guided waves propagating in PCFs can be easily characterized without any need for numerical computations. The validity of the method proposed here is confirmed by comparing the calculated results with those obtained by a full-vector finite-element method. |
