Using it, the relationship between refractive index and resonant wavelength of different concentrations from 0% to 70% glycerin solution are measured.

The resonant wavelength, which is a key parameter, has been calculated theoretically in terms of the conditions of surface plasmon resonance, and the maximum measurement range of optical fiber SPR sensors is given out while other parameters are fixed.

Through the measurement to different quality fraction glycerite,useful information is obtained that the resonant wavelength of SPR spectrum is changed with the refractive index of environmental media,and the feasibility is validated to detect environmental media using the sensor.

A wavelength-shared WDM-PON system;

A double-parameter measure method based on resonance wavelength λspr and resonance light intensity Rmin is presented.

SPR spectrum outputted property is obtained according to experimental results, Which resonance wavelength and the lowest light intensity reflectivity vary with the change of liquid refractive index and type.

The resonance wavelength and SPR amplitude were calculated.
