Abstract

A photonic crystal fiber based on sunface plasmon resonance（ SPR-PCF） sensor with a wide temperature range of high sensitivity dual-test material channel is proposed.Using SPR technology

the change of resonance wavelength is measured by the core loss spectrum to achieve the purpose of measuring different temperatures.And the structure is simple

easy for measurement operation

and the wavelength range of its operation can be adjusted.The experimental results show that the temperature measurement interval is-80 ℃ to 80 ℃

and the maximum spectral sensitivity of 3 nm/℃ can be obtained.The proposed fiber-optic sensing device has great research value in sensing field.
