Paper Abstract
We investigate the conduction intersubband linear response of a n-type quantum well driven by one or two infrared
optical fields with arbitrary strengths. The fields couple the third subband to the second energy subband and the
ground subband, forming a Λ system. We investigate the dependences of the absorption spectrum on the pump
field strengths. The results for the equal Rabi frequencies can be understood in terms of quantum coherence
processes of the intersubband transitions, such as coherent population trapping, and electromagnetically induced
transparency. The effects of different Rabi frequencies on the absorption spectrum due to fields are also discussed.
