Research

Light offers a versatile means of detecting changes in materials, biological samples, and the surrounding environment. By tailoring how optical fields interact with a sensing medium, photonic devices can translate small physical or chemical variations into measurable spectral responses. Our research brings together optical fibers, waveguide gratings, and resonators to explore sensing concepts for diverse applications.

Key interests include improving sensitivity, achieving selective and reliable detection, and distinguishing multiple parameters within a single device. We combine theoretical modeling and device optimization to understand sensing performance and address challenges such as temperature cross-sensitivity. These efforts support a broader vision of adaptable photonic sensing platforms for biomedical analysis, environmental monitoring, industrial measurements, and quality assessment.
