Enhanced Optical Nonlinearity and Very Rapid Response Due to Excitons in Quantum Wells and Dots

Abstract

Exciton is a coherent elementary excitation which is made by coherently superposing atomic excitations over a whole crystal in an ideal case. As a result, it has a macroscopic transition dipolemoment. Therefore these excitons are expected to contribute to strong optical nonlinearity.
