Ultrafast active control of optical transmission pseudomodes in a multiple scattering nanowire layer

摘要

We present results on experiments and theoretical modelling of light scattering in complex photonic media consisting of dielectric nanowires. Numerical finite-element calculations are used to investigate the frequency response of the transmission pseudomodes and corresponding frequency correlation in a random slab. We discuss our experiments demonstrating a new, ultrafast regime of phase breaking in stongly scattering nanowire materials. The new phase breaking phenomenon opens up avenues for ultrafast control of random lasers, nanophotonic switches, and photon localization.
