Efficient mode conversion in guiding structures with longitudinal modulation of nonlinearity

Abstract

We describe power-dependent dynamics of conversion of the guided modes of various guiding structures due to nearly resonant longitudinal modulation of the nonlinear coefficient of the medium. It is shown that the control of the energy exchange integrals, as well as of the input weights of the interacting modes is especially crucial for efficient mode conversion in the setting considered here. Complex dynamics of conversion incorporates various scenarios, including non-harmonic oscillations of the energy weights, which mimics Jacoby elliptical functions.
