Photonic Metamaterials: From Random to Periodic

Dynamics of photon localization

Abstract

A dramatic suppression of the leakage rate of electromagnetic energy and concomitant enhancements in intensity fluctuations and spatial correlation is observed with increasing time delay for localized waves and compared to models of transport.

We observe the increasing impact of weak localization and the growth of intensity correlation with delay time from an exciting pulse and find a link between localization and mesoscopic fluctuations of total transmission.

Strong-Field Kapitza-Dirac Scattering of Neutral Atoms

Sebastian Eilzer, H. Zimmermann, U. Eichmann

Laser induced strong-field phenomena in atoms and molecules on the femtosecond (fs) time scale have been almost exclusively investigated with traveling wave fields. In almost all cases, approximation of the strong electromagnetic field by an electric field purely oscillating in time suffices to describe experimental observations. Spatially dependent electromagnetic fields, as they occur in a standing light wave, allow for strong energy and momentum transfer and are expected to extend strong-field dynamics profoundly. Here we report a strong-field version of the Kapitza-Dirac effect for neutral atoms where we scatter neutral He atoms in an intense short pulse standing light wave with fs duration and intensities well in the strong-field tunneling regime. We observe substantial longitudinal momentum transfer concomitant with an unprecedented atomic photon scattering rate greater than 10(16)s(-1).

Statistics of Dynamics of Localized Waves

A. A. Chabanov, Azriel Z. Genack

The measured distribution of the single-channel delay time of localized microwave radiation and its correlation with intensity differ sharply from the behavior of diffusive waves. The delay time is found to increase with intensity, while its variance is inversely proportional to the fourth root of the intensity. The distribution of the delay time weighted by the intensity is found to be a double-sided stretched exponential to the 1/3 power centered at zero. The correlation between dwell time and intensity provides a dynamical test of photon localization.
