Abstract
Optical fiber tweezers have proven highly effective in precisely manipulating and trapping microscopic particles. Most existing demonstrations use single-mode fibers, which require tapered ends and are limited to single-particle control. Although multimode fibers (MMFs) can generate arbitrary structured light fields by transmitting multiple spatial modes simultaneously, inherent mode crosstalk renders the transmitted light field uncontrollable. In this study, we demonstrate MMF optical tweezers capable of manipulating and trapping multiple microspheres by projecting structured light, achieving performance comparable to that of holographic optical tweezers. By employing neural networks to guide active wavefront shaping and mitigate mode crosstalk, we achieved precise projection of structured light fields. Our experimental setup, which includes a green laser and a digital micromirror device, enabled the generation of focused and structured light through the MMF. We successfully manipulated single microspheres along a defined path and trapped multiple microspheres simultaneously using ring-shaped structured light. These results highlight the versatility and potential of MMF optical tweezers for advanced optical manipulation applications.
期刊介绍:
Optics and Lasers in Engineering aims at providing an international forum for the interchange of information on the development of optical techniques and laser technology in engineering. Emphasis is placed on contributions targeted at the practical use of methods and devices, the development and enhancement of solutions and new theoretical concepts for experimental methods.
Optics and Lasers in Engineering reflects the main areas in which optical methods are being used and developed for an engineering environment. Manuscripts should offer clear evidence of novelty and significance. Papers focusing on parameter optimization or computational issues are not suitable. Similarly, papers focussed on an application rather than the optical method fall outside the journal''s scope. The scope of the journal is defined to include the following:
-Optical Metrology-
Optical Methods for 3D visualization and virtual engineering-
Optical Techniques for Microsystems-
Imaging, Microscopy and Adaptive Optics-
Computational Imaging-
Laser methods in manufacturing-
Integrated optical and photonic sensors-
Optics and Photonics in Life Science-
Hyperspectral and spectroscopic methods-
Infrared and Terahertz techniques
