- Abstract
- We analyze the rotational dynamics of light driven nanorotors, made of nanotube bundles and
gold nanorods aggregates, with nonsymmetric shapes, trapped in optical tweezers. We identify two different
regimes depending on dimensions and optical properties of the nanostructures. These correspond to alignment
with either the laser propagation axis or the dominant polarization direction, or rotational motions caused by
either unbalanced radiation pressure or polarization torque. By analyzing the motion correlations of the trapped
nanostructures, we measure with high accuracy both the optical trapping parameters and the rotation frequency
induced by the radiation pressure. Our results pave the way to improved all-optical detection, control over rotating
nanomachines, and rotation detection in nano-optomechanics. (literal)
