Excitons: Linear and non-linear optical effects
Selection rules and polarization dependence properties of one- and two-photon optical spectrocopies to exciton states in semiconductors are briefly discussed. The non-local effects in the description of the exciton in semiconductors are also considered and their importance is shown by presenting a gauge-invariant calculation of the two-photon transition rates to 2p Wannier excitons states in a two-band model.
