Abstract
We report the first combination of far-infrared linear and nonlinear ( saturation) magnetoabsorption experiments on coupled subband Landau le vel excitations in a series of modulation-doped multiple coupled doubl e quantum well (MCDQW) structures. Linear spectroscopy was carried out with a Fourier transform spectrometer over a range of temperature, an d saturation spectroscopy was carried out with the free electron laser at UC Santa Barbara. Based on theoretical analysis, an electron lifet ime of approximately 1.2 ns was obtained.
