The trapping and detection of single atoms using a spherical mirror
New Journal of Physics, 2012 We fabricate a miniature spherical mirror for tightly focusing an optical dipole trap for neutral atoms. The mirror formation process is modelled to predict the dimensions for particular fabrication parameters.

Chirality in Optical Trapping and Optical Binding [PDF]
Photonics, 2015 Optical trapping is a well-established technique that is increasingly used on biological substances and nanostructures. Chirality, the property of objects that differ from their mirror image, is also of significance in such fields, and a subject of much ...

Enhanced optical trapping [PDF]
Optical Manipulation and Structured Materials Conference 2020, 2020 Optical tweezers have contributed substantially to the advancement of micro-manipulation. However, they do have restrictions, mainly the limited range of materials that yield to optical trapping. Here we propose a method of employing optically trapped objects to manipulate the surrounding fluid and thus particles freely diffusing within it.

Analysis of Confinement in Dual Spherical-Tapered Ended Fiber Optical Trap
Applied Sciences, 2022 In dual-fiber optical traps, two counter-propagating laser beams emitted from opposing laser fibers trap and manipulate particles. We describe the operation and performance of a dual-fiber optical trap created using spherical-tapered ended fiber ...

Review of Scientific Instruments, 2004 Since their invention just over 20 years ago, optical traps have emerged as a powerful tool with broad-reaching applications in biology and physics. Capabilities have evolved from simple manipulation to the application of calibrated forces on—and the measurement of nanometer-level displacements of—optically trapped objects.

Generation of Hybrid Optical Trap Array by Holographic Optical Tweezers
Frontiers in Physics, 2021 Enabled by multiple optical traps, holographic optical tweezers can manipulate multiple particles in parallel flexibly. Spatial light modulators are widely used in holographic optical tweezers, in which Gaussian point (GP) trap arrays or special mode ...
