Flexible manipulation of low-refractive-index particles based on customized Laguerre-Gaussian beams
Low-refractive-index (LRI) particles are of significant importance in numerous fields including physics, biomedicine, and material science. However, due to the repulsion of light, the effective manipulation of LRI particles remains a technically challenge. In this study, we propose and validate the customized Laguerre-Gaussian beams with adjustable topological charge, opening size and orientation for flexible manipulation of multiple LRI particles. Through experimental investigation, we demonstrated the superior efficacy of this method for the efficient collection and release of silica particles with varying diameters in an oil solution. Our research contributes to the understanding and manipulation of multiple LRI particles in vortex optical fields, with potential applications in drug delivery and nano-manipulation.
期刊介绍：
Optics Communications invites original and timely contributions containing new results in various fields of optics and photonics. The journal considers theoretical and experimental research in areas ranging from the fundamental properties of light to technological applications. Topics covered include classical and quantum optics, optical physics and light-matter interactions, lasers, imaging, guided-wave optics and optical information processing. Manuscripts should offer clear evidence of novelty and significance. Papers concentrating on mathematical and computational issues, with limited connection to optics, are not suitable for publication in the Journal. Similarly, small technical advances, or papers concerned only with engineering applications or issues of materials science fall outside the journal scope.
