A resonance technique for the calculation of guided modes in nonlinear optics (Planar and cylindrical geometry)

A summary of the research work carried out in our Laboratory, concerning the analysis of nonlinear optical waves guided by complicated planar/cylindrical structures, is reported here. The following configurations are chosen as representative examples: a) a scheme of successive non-Kerr nonlinear planar layers and b) a fiber waveguide consisting of successive nonlinear cylindrical layers. The methodology is based on the resonance technique and is simple and easily programmable on a small personal computer. The nonlinear media considered are of the general type (non-Kerr media) including the more complicated but realistic case of saturable media. A representative set of numerical results obtained by this method is demonstrated.
