We perform an experimental and theoretical investigation of the simultaneous optical trapping and rotation of spherulite-like chiral microparticles. The coupling of linear and angular momentum, mediated by the light spin and the microparticles chiral reflectance, allows for fine tuning of chirality-induced optical forces and torques. This offers novel tools for optomechanics, optical sorting and sensing, and optofluidics.

Abstract
We perform an experimental and theoretical investigation of the simultaneous optical trapping and rotation of spherulite-like chiral microparticles. The coupling of linear and angular momentum, mediated by the light spin and the microparticles chiral reflectance, allows for fine tuning of chirality-induced optical forces and torques. This offers novel tools for optomechanics, optical sorting and sensing, and optofluidics.File in questo prodotto:
