Project Title:

Topological structuring and optomechanics of liquid crystals using complex light fields endowed with spin and orbital angular momentum


We propose to develop two aspects of the optical control of liquid crystals in presence of wave or material singularities. The first aim topological structuring concerns the three-dimensional light-induced ordering of the director field in liquid crystals, with a particular emphasis on the generation of topological defects, which include the use of the orientational optical nonlinearities of liquid crystals. The second one optomechanics is related to the spatiotemporal optical manipulation of liquid crystal systems, which includes displacements and flows driven by light fields. Both objectives will be realized owing to the peculiar interaction of light with anisotropic and inhomogeneous fluids, liquid crystals, in presence of spin and orbital angular momentum of light.
