Orbital Angular Momentum Divider of Light
IEEE Photonics Journal, 2017 Manipulation of orbital angular momentum (OAM) of light is essential in OAM-based optical systems. In particular, the OAM divider, which can convert the incoming OAM mode into one or several new smaller modes in proportion at different spatial paths, is ...

The photonic wheel - demonstration of a state of light with purely transverse angular momentum [PDF]
Journal of the European Optical Society-Rapid Publications, 2013 In classical mechanics, a system may possess angular momentum which can be either transverse (e.g. in a spinning wheel) or longitudinal (e.g. for a spiraling seed falling from a tree) with respect to the direction of motion. However, for light, a typical

Trapping of light with angular orbital momentum above the light cone [PDF]
Advanced Electromagnetics, 2017 We consider bound states in the radiation continuum (BSC) above the light cone in an one-dimensional periodic array of dielectric spheres in air. The BSCs are classified by orbital angular momentum m, Bloch wave vector β directed along the array, and ...

Theory of angular momentum transfer from light to molecules
Physical Review ResearchWe present a theory describing the interaction of structured light, such as light carrying orbital angular momentum, with molecules. The light-matter interaction Hamiltonian we derive is expressed through couplings between spherical gradients of the ...
