Theoretical Study of Mechanical Control of Micro- and Nano-Mechanical Systems by Cavity-Induced Radiation Force

摘要

We theoretically investigate the possibility of controlling the vibration amplitude of a cantilever used in scanning probe microscopy (SPM) by cavity-induced radiation force (CIRF) exerted on the cavity mirror attached to It. It has been clarified that the amplitude of the cantilever can be decreased by one order of magnitude owing to the nonlinear dynamics induced by CIRF under weak laser Irradiation of 30 to 50μW. This mechanism would be applied to, for example, dynamical control of micro- and nano-mechanical systems, and high-sensitivity SPM based on small amplitude metrology.
