Coherent destruction of tunneling in waveguide directional couplers

It is theoretically shown that the phenomenon of coherent destruction of tunneling in bistable quantum systems induced by an external driving field can be realized in a periodically curved optical waveguide coupler, the periodic bending of the coupler simulating the effect of the external field in the quantum system.
