Paper Abstract

Coupled cantilevers are trapped by laser in a 3-mirror configuration. We studied the signal transduction between the cantilevers by laser control. A force or displacement sensor with such laser trapping technique could achieve much higher sensitivity, as high as 3-4 orders as compared to a single cantilever. We also studied the energy transfer processes by laser trapping and manipulation. Rabi oscillations are observed. Quantum analog Landau-Zener Tunneling and Landau-Zener-Stuckelburg interferometry are realized in the classical regime. We have proved that the energy or signals could be transferred from one cantilever to the other in the real-space by laser manipulation. Laser manipulated coupled cantilvers have great potentials in precision measurements and in quantum information processing.
