Sub-diffraction optical coherent control of ultrafast electrical currents in antenna devices on GaAs

Femtosecond omega /2 omega pulse pairs derived from a compact Er:fibre source induce coherently controlled currents in low temperature grown GaAs. They are characterized by analyzing charge accumulation at contacts closeby. We focus on the photoresponse of bowtie optical antennas integrated into suc...
