“…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

“…25, the exchange of momentum between light and matter, and therefore, the forces exerted on objects, is still dependent on the particularities of the situation. 24,27,29 Experimental results suggest that when an interface is present, the Minkowski formula should be used to correctly obtain the related optical force 14 (see Section 2 in Supplementary Information for details).…”

Photon momentum transfer in inhomogeneous dielectric mixtures and induced tractor beams

The determination of optical force as a consequence of momentum transfer is inevitably subject to the use of the proper momentum density and stress tensor. It is imperative and valuable to consider the intrinsic scheme of photon momentum transfer, particularly when a particle is embedded in a complex dielectric environment. Typically, we consider a particle submerged in an inhomogeneous background composed of different dielectric materials, excluding coherent illumination or hydrodynamic effects. A ray-tracing method is adopted to capture the direct process of momentum transfer from the complex background medium, and this approach is validated using the modified Einstein-Laub method, which uses only the interior fields of the particle in the calculation. In this way, debates regarding the calculation of the force with different stress tensors using exterior fields can be avoided. Our suggested interpretation supports only the Minkowski approach for the optical momentum transfer to the embedded scatterer while rejecting Peierls's and Abraham's approaches, though the momentum of a stably moving photon in a continuous background medium should be considered to be of the Abraham type. Our interpretation also provides a novel method of realizing a tractor beam for the exertion of negative force that offers an alternative to the use of negative-index materials, optical gain, or highly non-paraxial or multiple-light interference. Keywords: dielectric interface; Minkowski photon momentum transfer; modified Einstein-Laub method; optical pulling force; optical tractor beams INTRODUCTIONFollowing the pioneering work of Marston 1 in acoustics, optical 'tractor beams' have attracted considerable interest by virtue of their unusual mechanism for micromanipulation. [2][3][4][5][6][7][8][9][10][11][12][13] Generally speaking, a tractor beam is a customized light beam that exerts a negative scattering force (NSF) on a scatterer and pulls it opposite to the propagation direction of the light, in contrast to conventional pushing forces. 14 Optical pulling forces provide a novel approach to gradientless optical manipulation techniques distinct from optical tweezers, 15-17 optical conveyors 13,18,19 and nanooptomechanical systems. 20,21 Recently, various types of tractor beams have been experimentally demonstrated using a Gaussian beam with an optical mirror (involving the interference of incident and reflected light beams in certain limited regions) 8 and using dodecane droplets sitting on a dielectric interface. 22 However, in the presence of a high-powered laser, hydrodynamic effects (uneven heat dissipation, particle absorption, temperature gradients, liquid convection, surface energy wells, etc.) may also contribute. Moreover, the stability criteria for tractor beams, which are very important for practical application, have not yet been investigated.Although the mechanical effect has been demonstrated 22 to be an overall consequence of all possible contributing factors, the mechanism of the optical momentum transfer from a mixe...

“…The most notable advances include the use of diffractionless and/or engineered optical beams such as Bessel, 4,5 Airy, 6 optical lattices, 7 miniaturized fiber-optics tweezers 8 and electromagnetic fields in optically bounded structures. [9][10][11] These approaches stimulated observations of optical pulling forces 12 and optical lift 13 effects. Most recently, near-field optical forces have been explored in the chip-scale optical devices integrated with microfluidic systems.…”

Resonant light pressure effects can open new degrees of freedom in optical manipulation with microparticles, but they have been traditionally considered as relatively subtle effects. Using a simplified two-dimensional model of surface electromagnetic waves evanescently coupled to whispering gallery modes (WGMs) in transparent circular cavities, we show that under resonant conditions the peaks of the optical forces can approach theoretical limits imposed by the momentum conservation law on totally absorbing particles. Experimentally, we proved the existence of strong peaks of the optical forces by studying the optical propulsion of dielectric microspheres along tapered microfibers. We observed giant optical propelling velocities ,0.45 mm s 21 for some of the 15-20 mm polystyrene microspheres in water for guided powers limited at ,43 mW. Such velocities exceed previous observations by more than an order of magnitude, thereby providing evidence for the strongly enhanced resonant optical forces. We analyzed the statistical properties of the velocity distribution function measured for slightly disordered (,1% size variations) ensembles of microspheres with mean diameters varying from 3 to 20 mm. These results demonstrate a principal possibility of optical sorting of microspheres with the positions of WGM resonances overlapped at the wavelength of the laser source. They can be used as building blocks of the lossless coupled resonator optical waveguides and various integrated optoelectronics devices.
