摘要:
AbstractThe development of electronic and photonic devices operating in the many‐THz regime will require the invention of novel structure concepts and will implement physical processes different from those presently used in optoelectronics. An analysis is reviewed of the physical mechanisms that can be implemented to generate, propagate and detect femtosecond electrical signals in properly designed semiconductor quantum well structures. Also discussed are recent experimental investigations of these effects as well as the fundamental limitations caused by two photon absorptio

摘要:
AbstractThe coherent polarization of a Wannier exciton system, induced by a short incident resonant light pulse, is calculated within a formalism that takes into account explicitly the internal structure of excitions. By examining the phase‐space filling interactions among excitons, it is shown that the hydrogenic structure of excitions causes significant deviations in their coherent optical response when compared with the response of the traditional two‐level model of optical coherence. This suggests that photon echo experiments, which measure directly the coherent polarization, may provide information on the structure of Wannier excit

摘要:
AbstractKinetic equations for the density correlation and density‐density response function are derived. Solving these equations numerically and comparing its solution with the adiabatic approximation the change in the transmitted spectrum of a single electronic transition is calculated where a red‐shift can be obser

摘要:
AbstractEquations for the reduced density operator are evaluated. Investigating the subdynamics of nonrelevant observables a resolvent formulation is obtained selfconsistently for the screening part of the evolution superoperator in the athermal nonequilibrium. The analysis is taken in the limit of many collisional events and corresponds to an extension fo the RPA‐result. Thereby, the short memory approximation is improve
