Optical binding in white light

Opt Lett. 2015 Apr 15;40(8):1818-21. doi: 10.1364/OL.40.001818.

Abstract

We experimentally demonstrate, for the first time, binding of aerosols of various sizes and shapes in white light. The optomechancial interaction between particles is long range and is in the underdamped regime. Incoherency allows mitigation of interference fringes to enable monotonically changing the distance between particles from 60 μm to contact, constituting a parametrically controlled testbed for transition studies at new scales.
