Nano-Optics: Coherent Nonlinear Optical Response and Control of Single Quantum Dots

摘要

Work on this program is aimed at developing and understanding nano- optical structures with the specific goal of developing and applying quantum optical methods to characterize and manipulate the quantum states of these systems. The measurements have resulted in a number of publications which demonstrate key features of new quantum mechanical structures. These features include optically induced and detected quantum entanglement of two exciton states as well as a demonstration of a classical Bell state, a Rabi oscillations corresponding to full coherent control of the state of a single quantum dot. The measurements were then extended to show optically induced and quantum entanglement in self assembled quantum dots through the detection of Raman quantum beats. Finally, we developed and demonstrated the first low temperature near field optical microscopy using coherent nonlinear optical spectroscopy techniques to directly probe the transition dipole and map out the center of mass motion of an excitonic wave function.
