Single gradientless light beam drags particles as tractor beams. [PDF]
Physical Review Letters, 2011 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 particles all the way towards the light source.

Nonlinear generation of hollow beams in tunable plasmonic nanosuspensions
APL Photonics, 2023 We experimentally demonstrate that a probe beam at one wavelength, although exhibiting a weak nonlinear response on its own, can be modulated and controlled by a pump beam at another wavelength in plasmonic nanosuspensions, leading to ring-shaped pattern

Optics Express, 2013 We proposed a scheme to manipulate the Goos-Hänchen shift of a light beam reflected from the depletion-type device via external voltage bias. It is shown that the lateral shift of the reflected probe beam can be easily controlled by adjusting the reverse

Electron-beam spectroscopy for nanophotonics [PDF]
Nature Materials, 2019 Progress in electron-beam spectroscopies has recently enabled the study of optical excitations with combined space, energy and time resolution in the nanometre, millielectronvolt and femtosecond domain, thus providing unique access into nanophotonic ...

Abnormally autofocusing vortex Swallowtail Gaussian vector beam with low spatial coherence
New Journal of Physics, 2023 The precondition for the application of light beams is the ability to devise light distribution with high precision. Controlling more dimensions for structured light fields is an effective method to improve the ability to devise light distribution.
