Journal ArticleDOI
Optical vortices from liquid crystal droplets.
TL;DR: This work reports on the generation of mono- and polychromatic optical phase singularities from micron-sized birefringent droplets using liquid crystal droplets whose three dimensional architecture of the optical axis is controlled within the bulk by surfactant agents.
Journal ArticleDOI
Optofluidic sorting of material chirality by chiral light
TL;DR: It is experimentally demonstrated that material chirality can be passively sorted in a fluidic environment by chiral light owing to spin-dependent optical forces without chiral morphology prerequisite.
Journal ArticleDOI
Acoustic rotational manipulation using orbital angular momentum transfer.
Andreas Anhäuser,Andreas Anhäuser,Régis Wunenburger,Régis Wunenburger,Etienne Brasselet,Etienne Brasselet +5 more
TL;DR: A rotational acoustic streaming phenomenon that results from the acoustic angular momentum transfer to the host fluid is unveiled, and it is shown that it lowers the viscous torque, thereby restoring the torque balance.
Journal ArticleDOI
Photopolymerized microscopic vortex beam generators: Precise delivery of optical orbital angular momentum
TL;DR: In this article, a simple single beam interferometric technique is proposed to characterize the phase singularity of the generated vortex beams, and the experimental results are compared to simulations and a satisfying agreement is obtained.
Journal ArticleDOI
Dynamics of optical spin-orbit coupling in uniaxial crystals
Etienne Brasselet,Yana V. Izdebskaya,Vladlen G. Shvedov,Anton S. Desyatnikov,Wieslaw Krolikowski,Yuri S. Kivshar +5 more
TL;DR: The detailed dynamics of spin-to-orbital angular momentum conversion for a circularly polarized Gaussian beam propagating along the optical axis of a uniaxial crystal is studied theoretically and experimentally.
