Optimization of the effects of power dependent refractive indices in optical waveguides

摘要

The propagation of guided waves in planar optical waveguides characterized by an intensity dependent refractive index is analyzed. Closed form expressions for Dgr;bgr;k, the change in the propagation constant of the symmetric waveguide, were obtained using perturbation theory and were evaluated to predict optimum thickness for maximizing Dgr;bgr;. It is found that the maximum value of Dgr;bgr; is inversely proportional to the optimized thickness of the waveguide.
