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 ...

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 ...

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 ...

Vortex energy flow in the tight focus of a non-vortex field with circular polarization [PDF]
Компьютерная оптика, 2020 Using Richards-Wolf formulas, we show that an axisymmetric circularly polarized vortex-free field can be focused into a sharp subwavelength focal spot, around which there is a region where the light energy flow propagates along a spiral. This effect can
