Title

Nonlinear Absorption In A Gaas Waveguide Just Above Half The Band Gap

Abstract

Nonlinear absorption in a GaAs waveguide is measured with photon energies near half the band-gap energy by employing single-beam and pump-probe attenuation techniques. Two-photon absorption followed by free-carrier absorption are the dominant nonlinear absorption mechanisms that are included in a model that fits the experimental data. © 1994 IEEE
