Abstract

The mesoscopic effects on quantum correlations of photon pairs emitted by a microspherical particle composed of many quantum particles in a double Raman scheme are studied. Quantum Langevin formalism with noise operators is used to compute the nonclassical correlations between the Stokes and anti-Stokes photons, particularly the Glauber’s second-order cross- and self-correlation functions. The theory includes realistic situations of inhomogeneous field distributions of the pump and control laser fields as the result of the focusing effect of the microsphere as well as its linear dispersion. The results show that the photon correlations are affected by the size and density of the microsphere, the detection direction, and the detuning and strength of the laser fields. The self-correlation times of the quantum fields are significantly enhanced by the focusing effect of the microsphere with certain sizes.
