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

Conversion of a beam carrying fractionnal angular momentum in High-Harmonics Generation [PDF]
EPJ Web of Conferences, 2023 Exotic light fields combining non-trivial spin and angular momentum may not be eigenstates of either the spin or orbital angular momenta operators. For these fields, it is relevant to define a Generalized Angular Momentum operator of which they are ...

Torque of guided light on an atom near an optical nanofiber [PDF]
, 2019 We calculate analytically and numerically the axial orbital and spin torques of guided light on a two-level atom near an optical nanofiber. We show that the generation of these torques is governed by the angular momentum conservation law in the Minkowski

Angular Momentum of Leaky Modes in Hollow-Core Fibers
Fibers, 2022 It is known that angular momentum (AM) is an important characteristic of light, which can be separated into the spin (SAM) and orbital parts (OAM). The dynamical properties of the spin and orbital angular momentums are determined by the polarization and ...

Insensitivity of spin dynamics to the orbital angular momentum transferred from twisted light to extended semiconductors [PDF]
, 2015 We study the spin dynamics of carriers due to the Rashba interaction in semiconductor quantum disks and wells after excitation with light with orbital angular momentum. We find that although twisted light transfers orbital angular momentum to the excited
