Saturation behavior of intersubband optical transitions in /ital p/-typesemiconductor quantum wells is examined theoretically with the multibandeffective-mass model. Carrier-phonon scatterings are taken into account withinthe deformation-potential approximation. Deviation of the hole distributionfrom thermal equilibrium due to optical pumping is calculated by solvingcoupled rate equations. Pump-and-probe absorption spectra are also studied, andpossible applications for light-by-light modulation are discussed.
