[BOOK][B] Vortex laser beams

VV Kotlyar, AA Kovalev, AP Porfirev - 2018 - taylorfrancis.com
This book deals with theoretical bases of the modern optics division concerned with
coherent light fields with singularities characterized by phase uncertainty. Singular light …

Optical pulling force

J Chen, J Ng, Z Lin, CT Chan - Nature photonics, 2011 - nature.com
A photon carries k of momentum, so it may be anticipated that light will 'push'on any object
standing in its path by means of the scattering force,,. In the absence of an intensity gradient …

Generation of wavelength-independent subwavelength Bessel beams using metasurfaces

WT Chen, M Khorasaninejad, AY Zhu, J Oh… - Light: Science & …, 2017 - nature.com
Bessel beams are of great interest due to their unique non-diffractive properties. Using a
conical prism or an objective paired with an annular aperture are two typical approaches for …

Single gradientless light beam drags particles as tractor beams

A Novitsky, CW Qiu, H Wang - Physical review letters, 2011 - APS
Usually a light beam pushes a particle when the photons act upon it. We investigate the
optical forces by nonparaxial gradientless beams and find that the forces can drag suitable …

Origin, experimental realization, illustrations, and applications of Bessel beams: a tutorial review

AS Rao - arxiv preprint arxiv:2401.04307, 2024 - arxiv.org
Over the past 36 years much research has been carried out on Bessel beams (BBs) owing to
their peculiar properties, viz non-diffraction behavior, self-healing nature, possession of well …

Energy density and energy flux in the focus of an optical vortex: reverse flux of light energy

VV Kotlyar, AA Kovalev, AG Nalimov - Optics Letters, 2018 - opg.optica.org
Using the Richards–Wolf formulas for an arbitrary circularly polarized optical vortex with an
integer topological charge m, we obtain explicit expressions for all components of the …

Energy backflow in the focus of a light beam with phase or polarization singularity

VV Kotlyar, SS Stafeev, AG Nalimov - Physical Review A, 2019 - APS
We show that if a nonzero E-field intensity is found in the focus of a circularly polarized
optical vortex with phase singularity or a higher-order azimuthally polarized beam with …

Photon trajectories, anomalous velocities and weak measurements: a classical interpretation

KY Bliokh, AY Bekshaev, AG Kofman… - New Journal of …, 2013 - iopscience.iop.org
Abstract Recently, Kocsis et al (2011 Science 332 1170) reported the observation of'average
trajectories of single photons' in a two-slit interference experiment. This was possible by …

On the concept of “tractor beams”

S Sukhov, A Dogariu - Optics letters, 2010 - opg.optica.org
We demonstrate the existence of a class of optical beams where the nonconservative forces
can be locally oriented in a direction opposite to the propagation wave vector. Objects …
