Tweezers controlled resonator [PDF]

Optics Express, 2015
We experimentally demonstrate trapping a microdroplet with an optical tweezer and then enabling it as a microresonator by bringing it close to a tapered fiber coupler. Our tweezers facilitated the tuning of the coupling from the under-coupled to the critically coupled regime with an optical Q of 12 million and microresonator size at the 85 mirons scale.

Influence of Laser Intensity Fluctuation on Single-Cesium Atom Trapping Lifetime in a 1064-nm Microscopic Optical Tweezer [PDF]

Applied Sciences, 2020
An optical tweezer composed of a strongly focused single-spatial-mode Gaussian beam of a red-detuned 1064-nm laser can confine a single-cesium (Cs) atom at the strongest point of the light intensity.

Deep learning for optical tweezers

Nanophotonics
Optical tweezers exploit light–matter interactions to trap particles ranging from single atoms to micrometer-sized eukaryotic cells. For this reason, optical tweezers are a ubiquitous tool in physics, biology, and nanotechnology.

Comparing Femtosecond Optical Tweezers with Conventional CW Optical Tweezers [PDF]

arXiv
In this work, we present a comparative study between continuous-wave (CW) and pulsed optical tweezers for 250 nm, 500 nm and 1-micron radius polystyrene beads at 5 different laser powers. We have used a Ti:Sapphire (MIRA 900F) laser that can be easily switched from CW to pulsed mode of operation, so there is no change in the experimental conditions in ...

Movable surface acoustic wave tweezers: a versatile toolbox for micromanipulation [PDF]

Microsystems & Nanoengineering
Surface acoustic wave (SAW) tweezers are a promising multifunctional micromanipulation method that controls microscale targets via patterned acoustic fields. Owing to their device structure and bonding process, most SAW tweezers have limitations in terms

Optical tweezers in a dusty universe [PDF]

The European Physical Journal Plus, 2021
AbstractOptical tweezers are powerful tools based on focused laser beams. They are able to trap, manipulate, and investigate a wide range of microscopic and nanoscopic particles in different media, such as liquids, air, and vacuum. Key applications of this contactless technique have been developed in many fields. Despite this progress, optical trapping
