Nonlinear Optics in Quantum Confined Semiconductors

  • Paul Horan
  • Werner Blau


The field of nonlinear optics is dominated by the search for materials which show a large nonlinear optical response. Physical confinement of charge carriers, whether in 1, 2 or 3 dimensions, can greatly enhance the nonlinear optical behaviour. We have studied the nonlinear optical properties of small particles, in the size range 100–10ºA which provide 3-D charge confinement. The larger particles are too big to show signif-icant quantum confinement effects. Smaller particles show distinct confinement effects and significant optical nonlinearity.
