Paper Abstract

An alternative mechanism to produce an optical blue shift in a double quantum well heterostructure is suggested, distinct from that recently proposed by means of a static electric field1 . For this purpose we consider the tuning effects of the energy levels of the heterostructure due to the laser-dressing of the quantum well by a pulsed low-energy long-wavelength laser field. Appropriate parameters of the heterostructure are chosen so as to fulfil the necessary tuning conditions. Symmetric and asymmetric double quantum wells are discussed as well as the respective blue shifts attainable by different laser field strengths.
