Abstract

We propose a new mechanism for fiber optic high temperature sensing based on whispering gallery mode resonance in bent optical fibers. Due to the strong whispering gallery mode resonance in cladding-thinned bent optical fibers, long-period grating-like deep spectral peaks are formed in the wavelength domain. The wavelength shift of the resonance peaks as a function of temperature is investigated. It is demonstrated that the single loop of bend ring in the fibers can be used as a transducer for high temperature sensing without any internal structure.
