Nonlinear Optics and Coherent Optical Control of Single Electron Systems
Abstract
Work on this program was aimed at developing and understanding nano-optical structures with emphasis on developing quantum optical based devices. Specific work focused on semiconductor quantum dots. During this research period, a number of important discoveries were made as well as critical demonstrations of importance to future technology. The discoveries include the prediction and observation of spontaneous emission induced coherence and the unexpected control of nuclear field fluctuations through coherent electron spin trapping that reduced the nuclear fluctuations and increases the electron spin coherence time. Demonstrations include fast spin state initialization, coherent spin trapping, quantum dot tomography, and the Mollow absorption spectrum for neutral and negatively charged exciton. Future work will capitalize on this progress to demonstrate deterministic entanglement between the electron spin and a photon for quantum information transfer and entanglements between two electron in adjacent dots for quantum based logic devices, sensors and communications.
