About
Qijie Xie is a rising researcher in silicon photonics, with a focus on optical phased arrays (OPAs) for LiDAR systems—a critical technology for autonomous driving, surveying, and environmental sensing. His most-cited work, "Silicon-based optical phased array with a reconfigurable aperture for 'gaze' scanning of LiDAR" (2024, 18 citations), introduces a novel approach to LiDAR beam steering. Instead of pursuing dense point clouds for high-definition 3D imaging, Xie’s design reconfigures the OPA aperture to enable "gaze" scanning, prioritizing selective, adaptive scanning over brute-force resolution. This contribution addresses a key trade-off in LiDAR: balancing field-of-view, resolution, and scanning speed. By demonstrating a silicon-based platform with dynamic aperture control, Xie’s work advances the practicality of solid-state LiDAR for real-world applications. Though early in his career, his research is already shaping how next-generation LiDAR systems can achieve efficient, intelligent scanning—moving beyond conventional point-cloud density to more context-aware sensing. His work signals a promising trajectory in integrated photonics for autonomous systems.
