Název v původním jazyce

Surface plasmon resonance optical cavity enhanced refractive index sensing

Popis výsledku v původním jazyce

We report on a method for surface plasmon resonance (SPR) refractive index sensing based on direct time-domain measurements. An optical resonator is built around an SPR sensor, and its photon lifetime is measured as a function of loss induced by refractive index variations. The method does not rely on any spectroscopic analysis or direct intensity measurement. Time-domain measurements are practically immune to light intensity fluctuations and thus lead to high resolution. A proof of concept experiment is carried out in which a sensor response to liquid samples of different refractive indices is measured. A refractive index resolution of the current system, extrapolated from the reproducibility of cavity-decay time determinations over 133 s, is found tobe about 105??RIU. The possibility of long-term averaging suggests that measurements with a resolution better than 107??RIU/Hz are within reach.
