摘要：
This paper presents a metal-grating assisted surface Plasmon resonance based highly sensitive refractive index sensor for the detection of gases in wavelength interrogation mode. The structural parameters are optimized to get high sensing performance. The sensitivity is observed to be 9000 nm/RIU (refractive index units) for the ambient refractive index in the range 1.00-1.01. The structural parameters have shown the tunability of the resonant wavelength, sensitivity and figure of merit of the sensor in a wide range.
