Optical/Far-Infrared Control of Low-Dimensional Semiconductor Structures
Abstract
A program of research was carried out in which theoretical investigations into the simultaneous manipulation of carriers (electrons, holes, and ultimately excitons) and light in semiconductor nanostructures such as quantum wells were conducted. The manipulation of the carrier and optical dynamics will be achieved by the use of specially tailored ultrafast optical pulses, multicolor laser fields, millimeter or submillimeter electromagnetic pulses, or combinations of the above. Because the relevant time scale for the carrier dynamics may be less than the characteristic dephasing time of the carriers, the evolution of the system can be coherent; phase effects play a dominant role. Such shaped pulses and multicolor fields may be used to coherently control optical excitations in semiconductors in order to access quantum mechanical states, which are otherwise difficult to attain.
