Single-atom trapping and transport in DMD-controlled optical tweezers

New Journal of Physics, 2018
We demonstrate the trapping and manipulation of single neutral atoms in reconfigurable arrays of optical tweezers. Our approach offers unparalleled speed by using a Texas instruments digital micro-mirror device as a holographic amplitude modulator with a

Ultraprecise holographic optical tweezer array

Physical Review A
Neutral atoms trapped in microscopic optical tweezers have emerged as a growing platform for quantum science. Achieving homogeneity over the tweezers array is an important technical requirement, and our research focuses on improving it for holographic arrays generated with a Spatial Light Modulator (SLM).

Photothermal bubble: Dynamics, manipulation, and applications

Droplet, EarlyView.
As a versatile platform for bubble manipulation, photothermal techniques empower diverse operations: planar translation by scanning the laser spot, sustained periodic bouncing from competing thermal and hydrodynamic flows, and even guided 3D trajectories achieved by tailoring the heating configuration.

Enantioselective Separation and Negative Transport of Chiral Particles via Optical Needle Fields

Nanophotonics, Volume 15, Issue 13, 13 July 2026.
This work proposes an all‐optical strategy that leverages a tailored optical needle field for the enantioselective separation and 3D manipulation of chiral particles. By introducing phase modulation, we engineer a dual‐needle configuration capable of spatially separating and negatively transporting both enantiomers within a single system, offering a ...

Optically Selective Photomask Based on Field‐Induced Periodic Defect Arrays in Ferroelectric Nematics

Advanced Optical Materials, Volume 14, Issue 12, 25 March 2026.
Field‐induced periodic defect patterns in the ferroelectric nematic liquid crystal phase act as optically selective photomasks. Created in the liquid crystal cells with bare electrodes, their periodicity is controlled by the applied frequency and cell gap. When used as photomasks, these patterns modulate transmitted light, whose spatial characteristics
