Abstract: The working principle of the optic fiber surface plasmon wave (SPW) sensor is based on the resonance of the surface plasmon. A layer of the electronic gas exits on the surface of the sensor. When the environment temperature rises, the density of the electronic gas will increase and the kinetic energy of electronic gas will become stronger. Finally, the resonant frequency of the electronic agglomerate will change. The relationship between the resonant wavelength and the environment temperature is found through experiments and the error is analyzed. the application of the optic fiber SPW sensor is thus broadened.

Key words: temperature, kinetic energy, optic fiber SPW sensor, electronic gas, density
