Abstract :

Nano-optical excitations often correspond to inhomogeneous fields and complex beam structures that can lead to a great variety of effects. This is in particular the case in surface plasmon optics, where the spinning character of a plasmonic field brings a clear distinction between orbital and spin energy flows. Such a distinction has fundamental implications in the context of optical forces, in particular when chirality becomes a key player. The possibility to use unexpected modes of actuations in order to selectively manipulate chiral objects at the nanoscale opens new perspectives that we are currently exploring with optical trapping experiments.
