Local-field effect in the biexciton system in CuCl

Abstract

We show that the inclusion of the local-field effect in the calculation of the nonlinear dielectric function of CuCl near the biexciton resonance does not yield bistability on reflection as suggested by Abram and Maruani.

Analysis of biexcitonic optical bistability in CuCl in the presence of collision broadening

Dror Sarid, Nasser N. Peyghambarian, H. M. Gibbs

The dielectric function of CuCl in the presence of biexciton formation that involves collision-broadening effects is analyzed in terms of incident photon energy and intensity. We discuss the nonlinear response of the material and its application to bistable devices.

Optical bistability of a dense exciton-biexciton system: CuCl

Chi C. Sung, C. M. Bowden

The steady-state solution of the Langevin equation for a dense exciton-biexciton system is investigated. The corrections to the previous work, the contribution of the field---exciton-biexciton interaction, and the local-field correction are shown to modify the threshold of optical bistability significantly.

Optical Bistability in CuCl

B. Hönerlage, J.‐Y. Bigot, R. Lévy

As it is well known from nonlinear optics, the dielectric function ε( Q ˜ ,ω) and the resulting polariton dispersion are functions of the excitation intensity. Since in CuCI biexcitons with energy EBi may be created by the absorption of two photons provided by different light sources, ε( Q ˜ , Ω ) depends on the density of photons with frequency ωℓ, defined such that.

Observation of Biexcitonic Optical Bistability and Optical Limiting in CuCl

Experimental evidence for the occurrence of optical bistability using the biexciton two-photon resonance in CuCl is presented. These observations agree with recent theoretical predictions that require an intensity of 10 MW/${\mathrm{cm}}^{2}$ and 10-\ensuremath{\mu}m-thick etalons with 90% reflective coatings. Earlier much less demanding predictions neglected two important physical effects: unsaturable background absorption at the biexciton from the tail of the exciton resonance and broadening of the biexciton resonance with intensity.
