Time Resolved spectroscopy of Coherent Switching in GaAs/A1GaAs Coupled Double Quantum Wells,
Abstract
In the past several theoretical and experimental approaches for the design of optical computing devices have been given. Common to that devices is that they are at least bistable, so that they can be switched by a light pulse from one state into an other with or without an additional external electric field. Mahler) have proposed a device consisting of quantum dots with slightly detuned quantization energies, representing two eigen states that can be coherently switched by a laser pulse of appropriate energy and duration. Although technology is not so far to produce these structures with the high accuracy necessary, some of the basic features can in principal also be studied in 2-dimensional systems.
