Abstract
In AIGaAs all-optical switching devices, when operated at wavelengths too far below half the band gap, three-photon absorption appears to become a limiting factor for all-optical switching.1 In this work, we show using the two-parabolic-band model and experimental results that there is only a limited spectral range below half the bandgap in AIGaAs (and presumably all semiconductors) in which the bound electronic optical nonlinearity can be used without significant multiphoton absorption.
