Freestanding Nanomembrane Sensor Reads Ultranarrow Quasi-BIC Resonances Through Light Emission

Researchers developed an emission-based refractometric sensor that couples the defect-related photoluminescence of a freestanding silicon nitride nanomembrane to high-Q quasi-BIC modes. The device resolved refractive-index changes as small as ?n = 0.001 in water and achieved a figure of merit of 250, while simulations showed that its sensitivity is concentrated near the membrane surface.
