An echo of an exciting light pulse in quantum wells
Abstract
The non-sinusoidal character oscillations appear in the transmitted, reflected and absorbed light fluxes when light pulses irradiate a semiconductor quantum well (QW), containing a large number of the equidistant energy levels of electronic excitations. A damping echo of the exciting pulse appears through the time intervals 2π/ΔE in the case of the very short light pulses γl-1/ΔE.
