Abstract

In this paper, we examine the modification of specific nonclassical properties of the sphere coherent state upon perpendicular propagation through an absorptive and dispersive dielectric slab at finite temperature. To achieve this purpose, by describing the dielectric dispersion of the slab by Lorentz model, the quadrature squeezing and the Mandel parameter are evaluated for the transmitted state. A generalization of the single-mode sphere coherent state to a continuum-mode is considered. The degree of second-order coherence is calculated for a continuum sphere coherent state, and the quantum noise effects produced by transmission through the slab on the antibunching feature are examined. We find that near the medium resonance the detrimental effect of the loss and thermal fluctuations of the slab are not compensated with increasing the physical space curvature of the incident state.
