Time Reversal Coherent Control for Positioning and Foucusing in Nanoplasma
An approach has been introduced called time reversal to coherently control the position in which the optical energy localizes in plasma nanosystems.This approach is based on the impulsive localized excitation of the nanosystem and time reversal of the generated far-zone field at a single point with one polarization.Despite strong interaction and significant dephasing and dissipation in metal plasma systems,and incompleteness of this time reversal,the proposed approach proves to be very efficient in controlling the nanoscale optical fields.The approach may be applied in nanoscales spectroscopy,optical modification,ultradensememory,and information processing on the nanoscale.
