The authors have shown that excitonic polaritons are two-mode intrinsically squeezed states of certain bosons A contained in . They give the wavevector (frequency) dependence of the squeezing factor. They predict the fluctuations in time of the polariton wave probability density distribution and they calculate the time interval during which squeezing occurs. For experimental detection of polariton squeezing they extend a proposal of B Yurke, see Phys. Rev. Lett., vol.60, p.2476, eqn.6 (1988) by showing that via frequency tuning the vanishing of the particle-polariton scattering cross section can be achieved. They illustrate some results for the case of CdS.
