Abstract Excitonic saturable absorption on iron-doped InGaAs/InP multiple-quantum-well structures is studied by Fourier transform infrared spectroscopy and pump-probe measurement in the 1.55 {mu}m wavelength range. The recovery time of the excitonic absorption bleaching is improved by iron doping and is found to vary from 7 ns on the undoped sample to 7 ps on the highest doped sample. The samples exhibit high optical switching with a differential optical transmission coefficient of more than 20% and a saturation fluence smaller than 47 {mu}J/cm2. Furthermore, we notice no degradation of the contrast ratio due to iron doping. {copyright} 2001 American Institute of Physics.
