The Integrated Photonics and Intelligent Sensing Laboratory (IPIS Lab) focuses on guided-wave and integrated photonic technologies for next-generation optical sensing and intelligent photonic systems. Our research spans optical waveguide gratings, interferometric and multimode photonics, non-Hermitian and time-modulated photonic systems, AI/ML-assisted sensing, and precision optical instrumentation. We develop advanced photonic platforms for environmental, biochemical, and physical sensing applications, with emphasis on sensitivity enhancement, robustness, and intelligent signal processing.
