Ratchet effect in lateral plasmonic crystal: Giant enhancement due to interference of "bright" and "dark" modes

I. V. Gorbenko, S. O. Potashin, V. Yu. Kachorovskii

We develop a theory of the ratchet effect in a lateral plasmonic crystal (LPC) formed by a two dimensional electron gas under a periodic dual-grating gate. The system is driven by…
