Abstract
The enhancement of the excitonic oscillator strengths and excitonic non-linearities, by spatial confinement, has made already possible a novel class of exciton-based optoelectronic devices (SEED,FETOM). Numerous processes contribute to the optical non-linearity, Some involve the filling of single particle states of the Fermions that compose the excitons, while others are produced by exciton-exciton or exciton-high-density plasma interactions. Most non-linear optical experiments show a cumulative effect due to all sources of nonlinearities.
