Recently, Pan Deng, a promising young instructor at the National Key Laboratory of Opto-Electronic Information Acquisition and Protection Technology, Anhui University, has collaborated with a research team from the University of Science and Technology of China. Together, they have introduced a cutting-edge femtosecond laser hybrid fabrication technique tailored for fiber-based integrated devices. Leveraging this innovative approach, they have successfully crafted a three-dimensional (3D) optical fiber microtweezer at the terminus of a conventional optical fiber. This breakthrough enables highly precise, minimally invasive, and programmable 3D manipulation of micron-scale objects.

The groundbreaking research findings have been featured in the esteemed international journal, Nature. Notably, the 3D optical fiber microtweezer developed by the research team boasts an output force that surpasses that of traditional optical tweezers by more than 100,000 times. This remarkable enhancement facilitates the meticulous manipulation of micron-scale targets and the precise assembly of intricate microstructures, marking a significant leap forward in the field.
