Abstract

We have observed saturation of absorption and gain in ensembles of InAs/GaAs self-assembled quantum dots at room temperature with continuous-wave driving in the 1.24-1.28 mu m wavelength range. The saturation intensity was found to be I-sat=(1.4-4.5) X 10(9) W/m(2) in absorption and I-sat =(0.2-3.8)X10(9) W/m(2) in gain, depending on the detuning. (C) 2010 American Institute of Physics.
