Thermal fluctuation analysis of singly optically trapped spheres in hollow photonic crystal cavities

M. Tonin, F. M. Mor, L. Forró, S. Jeney, and R. Houdré

We report on the behaviour of singly optically trapped nanospheres inside a hollow, resonant photonic crystal cavity and measure experimentally the trapping constant using back-focal plane interferometry. We observe two trapping regimes arising from the back-action effect on the motion of the nanosphere in the optical cavity. The specific force profiles from these trapping regimes is measured.
