Structured Light Beams With Fractional Topological Charge

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT In this paper, we develop a simple method to obtain solutions of the Helmholtz equation that holds fractional topological charge. Such wavefields are obtained in a closed and analytical form through the superposition of beams with integer topological charge.

Optical tweezers: wideband microrheology

, 2010
Microrheology is a branch of rheology having the same principles as conventional bulk rheology, but working on micron length scales and micro-litre volumes.

Orbital Angular Momentum Holography Using Neural Network and Camera in the Loop

Laser &Photonics Reviews, Volume 19, Issue 19, October 7, 2025.
Neural network and optimization‐based approaches are introduced for Orbital Angular Momentum (OAM) multiplexed holography, enabling high‐capacity, phase‐only image reconstruction. A Camera‐In‐The‐Loop (CITL) system learns a realistic propagation model to correct system imperfections.

Combined holographic-mechanical optical tweezers: Construction, optimization, and calibration

Review of Scientific Instruments, 2009
A spatial light modulator (SLM) and a pair of galvanometer-mounted mirrors (GMM) were combined into an optical tweezers setup. This provides great flexibility as the SLM creates an array of traps, which can be moved smoothly and quickly with the GMM.

Partial synchronisation of stochastic oscillators through hydrodynamic coupling

, 2012
Holographic optical tweezers are used to construct a static bistable optical potential energy landscape where a Brownian particle experiences restoring forces from two nearby optical traps and undergoes thermally activated transitions between the two ...

Expanding the toolbox for nanoparticle trapping and spectroscopy with holographic optical tweezers [PDF]

, 2012
We have developed a workstation based on holographic tweezers to optically trap, move and characterize metal nanoparticles. Our advanced darkfield imaging system allows us to simultaneously image and take spectra of single trapped metal nanoparticles. We

How to Manufacture Photonic Metamaterials

Advanced Materials Technologies, Volume 10, Issue 18, September 18, 2025.
Metamaterials boast applications such as invisibility and “hyperlenses” with resolution beyond the diffraction limit, but these applications haven’t been exploited in earnest and the market for them hasn’t grown much likely because facile and economical methods for fabricating them without defect has not emerged.

Holographic assembly of quasicrystalline photonic heterostructures

, 2005
Quasicrystals have a higher degree of rotational and point-reflection symmetry than conventional crystals. As a result, quasicrystalline heterostructures fabricated from dielectric materials with micrometer-scale features exhibit interesting and useful ...

Optical ordering of nanoparticles trapped by Laguerre-Gaussian laser modes [PDF]

, 2006
In earlier work, it has been established that laser-induced coupling between a pair of nanoparticles can enable the generation of novel patterns, entirely determined and controlled by the frequency, intensity, and polarization of the optical input.
