Refractive index resolution is an important indicator for a wavelength interrogation surface plasmon resonance sensor, which can be affected by signal-to-noise ratio. This paper investigates the impact of spectral signal-to-noise ratio on a surface plasmon resonance sensor. The effects of different spectral powers and noises are compared and verified through simulation and experiments. The results indicate that the optimal resonance wavelength is changed and the refractive index resolution can even be nearly twice as good when the spectral signal-to-noise ratio is increased. The optimal resonance wavelength can be found by changing the spectral power distribution or noise.

Difference Time

Abstract The performance of localized surface plasmon resonance-based sensor with and without Bragg grating by using finite difference time domain method is evaluated with nanoparticles used at the tip of optical fiber. The proposed sensor has been analyzed in terms of refractive index (RI) sensitivity and signal-to-noise ratio (SNR). It is observed that the RI sensitivity of surface plasmon resonance sensor is 240 nm/RIU with and without grating as RI of surrounding varies from 1.4 to 1.5. It is found that the value of SNR is 0.875 RIU→1 without grating and 2.75 RIU→1 with grating. So there is an improvement in the SNR when the Bragg grating is inscribed within the core of the fiber.
