About

Hongxiang Lei is a leading researcher in optical manipulation and nanophotonics, with a particular focus on scanning optical tweezers and their applications in color tuning technologies. His most-cited work, "Color Tuning Using Scanning Optical Tweezers" (2023, 6 citations), introduces a novel approach to nonemissive color display by directly mixing colors through optical trapping and manipulation of micro- and nanoparticles. This method offers a low-cost, low-energy alternative to traditional display technologies, eliminating the need for complex structural designs. Lei’s contributions bridge fundamental optical physics with practical applications in painting, printing, decoration, and animation display. By leveraging the precision of optical tweezers, he has demonstrated a scalable technique for dynamic color control, which holds promise for next-generation reflective displays and adaptive camouflage systems. His work is particularly notable for its simplicity and efficiency, addressing key challenges in energy consumption and manufacturing complexity. With a growing citation impact, Lei continues to advance the field of optical trapping, positioning himself as a key innovator in the intersection of photonics and materials science.
