TLDR
A new type of mechanism for enhanced optical nonlinearities and intrinsic optical bistability that relies on the combination of intrinsic feedback due to local field effects and excitonic resonances in semiconductor crystallites is proposed.Abstract:
We propose a new type of mechanism for enhanced optical nonlinearities and intrinsic optical bistability that relies on the combination of intrinsic feedback due to local field effects and excitonic resonances in semiconductor crystallites. These effects will be further enhanced by quantum confinement in small crystallites.read more
