Passive laser irradiation as a tool for optical catalysis [PDF]
, 2020 The mechanisms of absorption, emission, and scattering of photons form the foundations of optical interactions between light and matter. In the vast majority of such interactions there is a significant interplay and energy exchange between the radiation ...

Localized optical manipulation in optical ring resonators
Optics Express, 2015 We propose a tunable optical trapping system for nanoparticles based on generating standing wave by coupling two coherent beams into a ring resonator in opposite directions, respectively. The distributions of the mode field excited in three types of the ring-resonators-based trapping systems (microring, microdisk and slot ring) and the corresponding ...

Optical Trapping and Manipulation [PDF]
, 2010 A number of applications of microsystem technology require manipulation with high accuracy. Microreactors and microdiagnostic devices can be easily constructed with millimetre accuracy [1], but micrometre precision appears also to be realistic (see for example Fig. 3 below).

Independent trapping and manipulation of microparticles using dexterous acoustic tweezers [PDF]
, 2014 An electronically controlled acoustic tweezer was used to demonstrate two acoustic manipulation phenomena: superposition of Bessel functions to allow independent manipulation of multiple particles and the use of higher-order Bessel functions to trap ...
