NONLINEAR EXCITONIC OPTICAL-ABSORPTION IN GAINAS/INP QUANTUM-WELLS

NONLINEAR EXCITONIC OPTICAL-ABSORPTION IN GAINAS/INP QUANTUM-WELLS

We have studied the saturation of optical absorption in GaInAs/InP quantum wells at room temperature. Using optical excitation from a tunable cw Co:MgF2 laser, we find a saturation intensity of 70 W cm -2 when exciting resonantly at the n=1 heavy-hole exciton, and we deduce values of the nonlinear a...
