About

Yuanbo Xu is a rising researcher in the field of nanophotonics, with a focus on active beam steering and photonic-crystal surface-emitting lasers (PCSELs). His work addresses a critical challenge in optoelectronics: achieving compact, on-demand directional light emission without relying on bulky assemblies of passive optical antennas and external sources. In his 2024 paper, Xu demonstrates a novel approach to active beam steering directly from the laser source, offering a pathway toward more integrated and efficient devices for applications in optical communication, LiDAR, and display technologies. While still early in his career—with his most-cited paper currently garnering 3 citations—Xu’s contributions signal a promising direction for next-generation, chip-scale photonic systems. His research sits at the intersection of laser physics, metamaterials, and integrated photonics, and is likely to attract growing attention as the demand for compact, agile light sources intensifies. Xu’s work represents a meaningful step toward unifying emission and steering functions in a single, active nanophotonic platform.
