Paper Abstract

Thermoreversible compounds have been investigated for applications as a transducer in a fiber-optic temperature sensor utilizing a 2×2 fiber optic coupler. The dependence of the reflected optical power on the temperature has been studied. The reflected optical power at 632.8 nm indicated a monotonous change in the temperature range of observation, corresponding to 2.05dB increase in the optical power when the temperature increased from 20°C to 134°C. The temperature dependence of the optical properties was found to be reversible, which indicates that the temperature transducer is reversible as well.
