Impact of absorption mechanisms on Kerr-nonlinear resonator behavior

Abstract

The effect of both single-photon and two-photon absorption mechanisms on the Kerr-nonlinear behavior of resonant structures is investigated using a semianalytical, one-dimensional model. In particular, two-photon effects may severely degrade the ultrafast, nonlinear potential of these structures. Based on this model, the feasibility of Kerr-nonlinear operation is derived for the AlGaAs and Si material systems.
