Quantum Optical Studies of Semiconductors
Abstract
Work on this program focused on the development and application of advanced optical spectroscopy and methodology for the study of the quantum optical properties of semiconductor heterostructures. The work includes the first observation of the nonlinear optical polariton reflecting the complex nature of exciton-exciton interactions as well as the first observation of the light-hole-heavy-hole exciton Raman coherence. The program then moved toward the study of quantum dots, and reported the first observation of the coherent nonlinear optical response from a single quantum dot exciton as well as the first demonstration of the coherent optical control and exciton wave function engineering in a single quantum dot. The work also provides the first demonstration of optically induced Zeeman coherence and two-electron entanglement in a single dot. Finally, we developed a nonlinear optical near field scanning microscope for directly probing nano-optical structures. The first data from this system is remarkable and provides a mapping of the center-of-mass of the wave function of a localized exciton.
