Theory of Optical Tweezers [PDF]
Europhysics Letters (EPL), 1999 We derive a partial-wave (Mie) expansion of the axial force exerted on a transparent sphere by a laser beam focused through a high numerical aperture objective. The results hold throughout the range of interest for practical applications.

Optical Frequency Tweezers [PDF]
Physical Review Applied, 2022 We show a concept of optical frequency tweezers for tweezing light in the optical frequency domain with a high resolution, which is the frequency version of the optical tweezers for spatial manipulation of microscopic objects. We report the proof-of-principle experiment via frequency conversion inside a cavity only for the converted light.

Interferometric Optical Tweezers [PDF]
Optics and Photonics News, 1996 Abstract We report the first experimental demonstration of an optical trap that uses interference fringes for the trapping and micro-manipulation of microscopic objects. The finges can be generated either by two-beam interference or by projecting a reduced image of a Ronchi ruling on the sample plane.

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 ...

Simulation of superresolution holography for optical tweezers [PDF]
, 2008 Optical tweezers manipulate microscopic particles using foci of light beams. Their performance is therefore limited by diffraction. Using computer simulations of a model system, we investigate the application of superresolution holography for two ...

Accounting for polarization in the calibration of a donut beam axial optical tweezers. [PDF]
PLoS ONE, 2018 Advances in light shaping techniques are leading to new tools for optical trapping and micromanipulation. For example, optical tweezers made from Laguerre-Gaussian or donut beams display an increased axial trap strength and can impart angular momentum to
