    Abstract

    The effects of three-photon absorption on nonlinear directional coupling in semiconductors below half the gap are studied for both cw and sech 2 pulse signals. The figure of merit associated with three-photon absorption includes not only material properties but also device design parameters. Numerical results show that at high powers, three-photon absorption significantly degrades nonlinear coupling, reduces throughput, and distorts output pulses. Good agreement is found between the theoretical model and experimental data.
