We consider a biased molecular junction subjected to external time-dependent electromagnetic field. The field for two typical junction geometries (bowtie antennas and metal nanospheres) is calculated within finite-difference time-domain technique. Time-dependent transport and optical response of the junctions is calculated within nonequilibrium Green's-function approach expressed in a form convenient for description of multilevel systems. We present numerical results for a two-level (highest occupied molecular orbital-lowest unoccupied molecular orbital) model and discuss influence of localized surface plasmon-polariton modes on transport.
