Slow light in saturable absorbers

B. Macke, Bernard Ségard

In connection with the experiments recently achieved on doped crystals, biological samples, doped optical fibers, and semiconductor heterostructures, we revisit the theory of the propagation of a pulse-modulated light in a saturable absorber. Explicit analytical expressions of the transmitted pulse are obtained, enabling us to determine the parameters optimizing the time-delay of the transmitted pulse with respect to the incident pulse. We finally compare the maximum fractional delay or figure of merit so attainable to those which have been actually demonstrated in the experiments.

Reflection and absorption of QWs irradiated by light pulses in a strong magnetic field

Korovin, I. G. Lang L. I., Contreras-Solorio, D. A., S. T. Pavlov

It has been shown that the non-sinusoidal character oscillations appear in the transmitted, reflected and absorbed light fluxes when light pulses irradiate a semiconductor quantum well (QW), containing a set of a large number of the equidistant energy levels of electronic excitations. The oscillation amplitude is comparable to the flux values for the short pulses, duration of which γ_l^{-1} \leq \hbar/ΔE. A damping echo of the exciting pulse appears through the time intervals 2π\hbar/ΔE in the case of the very short light pulses γ_l^{-1}\ll \hbar/ΔE. Symmetrical and asymmetrical pulses with a sharp front have been considered. Our theory is applicable for the narrow QWs in a strong magnetic field, when the equidistant energy levels correspond to the electron-hole pairs with different Landau quantum numbers.

The non-sinusoidal character oscillations appear in the transmitted, reflected and absorbed light fluxes when light pulses irradiate a semiconductor quantum well (QW), containing a large number of the equidistant energy levels of electronic excitations. A damping echo of the exciting pulse appears through the time intervals $2π\hbar/ΔE$ in the case of the very short light pulses $γ_l^{-1}\ll\hbar/ΔE$.
