“…This allows us to envision applications for the pharmaceutical industry related to the ability to sort materials with different chiralities. Nanoactuation driven by optical radiation pressure [27] is another topic that may benefit from such a polarization control, as discussed in the few dedicated theoretical studies reported so far [14,28]. Finally, at a larger spatial scale, our findings emphasized the spin angular momentum of light as a novel ingredient to drive solar sails [29].…”

International audienceWe report on the full control of the optical radiation pressure at fixed photon flux and incident angle by the photon spin. This is done by using transparent chiral liquid crystal droplets that enable a strong coupling between the linear and angular degrees of freedom of a light field. From these results, we anticipate optical sorting of particles with different chirality as well as novel optical trapping and micromanipulation strategies

Adaptive Holography in Liquid Crystal Light-Valves

By performing two-wave mixing experiments in a liquid crystal light-valve, optical beam amplification is obtained as a strongly resonant process to which a narrow frequency bandwidth is associated. This property is exploited to realize adaptive holographic interferometric systems able to efficiently detect displacements as small as fraction of picometers. Pressure radiation induced deformations of a reflecting membrane are measured with the same type of system. Then, when used with complex wavefronts, like speckle fields, the LCLV-based interferometer allows to detect extremely small phase modulations. The examples shown demonstrate the potentialities of the light-valve for dynamic holography applications.

“…Light can exert forces of the order of 200 pN and is therefore used to manipulate atoms, molecules, and even biological cells [3,4]. Light pressure is also used for spectroscopic examination of vapors and gases [5] as well as for precision control of the positions of macroscopic objects [6]. Light pressure thus is an essential phenomenon for nanotechnologists to know and exploit.…”
