Influence of an absorbing dielectric background on bistable response of a dense collection of two-level atoms

Denis V. Novitsky

The stationary problem of light interaction with a dense collection of two-level atoms embedded in a dielectric is treated semiclassically. The effect of dielectric absorption on the phenomenon of intrinsic optical bistability is discussed in terms of the complex local-field enhancement factor. The calculations accounting for propagation effects (nonlocal regime) show that even low dielectric absorption results in the elimination of response instabilities.

Steady-state pulse propagation in inhomogeneously broadened absorbers in the presence of a Kerr nonlinearity

We consider the effect of a background dielectric on the steady-state propagation of a laser pulse through inhomogeneously broadened two-level atoms embedded in the dielectric. Because this problem apparently does not admit of analytic solutions, we have solved it numerically. A comparison of our results with the known analytic solutions for the homogeneously broadened atomic line shows that the two are similar. It seems that the new numerical solutions, unlike those for the homogeneous line, are not factorable, a fact to which we ascribe the difficulty in finding analytic solutions. We have found that as the atomic line broadens, the pulse widens and its height decreases, maintaining its area virtually constant.We consider the effect of a background dielectric on the steady-state propagation of a laser pulse through inhomogeneously broadened two-level atoms embedded in the dielectric.

Local-field effects in a dense collection of two-level atoms embedded in a dielectric medium: Intrinsic optical bistability enhancement and local cooperative effects

Michael E. Crenshaw, Charles M. Bowden

We investigate the effect of a linear host medium on the dynamics of a dense collection of resonant atoms. We find that near dipole-dipole interaction is enhanced by the presence of the host dielectric, resulting in a lower threshold density and a greater hysteresis area for intrinsic optical bistability. Cooperative decay terms appear that represent the interaction of near dipoles mediated by the absorptive component of the dielectric function of the host medium. These terms are part of the local response and correspond to local cooperative decay effects. \textcopyright{} 1996 The American Physical Society.We investigate the effect of a linear host medium on the dynamics of a dense collection of resonant atoms.
