Nonlinear self-phase-modulation effects: a vectorial first-order perturbation approach.
A full-vectorial integral expression is derived to compute the effective mode area of any Kerr-type nonlinearoptical waveguide working in a self-phase-modulation regime. In order to highlight the correction brought by the vectorial approach in a strong guidance situation, we compare the effective area of a tapered fiber computed by the usual scalar expression with the one obtained with the full-vectorial approach.
