Abstract
In this paper, we investigated the temperature sensing properties of self-phase modulation (SPM) combined with solitons in photonic crystal fibers by experimental verification. Pumped in the normal dispersion region close to the zero-dispersion point, SPM allows the resulting spectrum to extend into the normal dispersion region, generating solitons. By detecting the wavelength shift of the soliton at 900 nm, 2.366 W, the maximum sensitivity is 0.98 nm/°C. To the best of our knowledge, this is the first study of temperature sensing using SPM in combination with solitons, which broadens the boundaries of nonlinear-based sensors and holds considerable promise for high-performance temperature detection in a variety of demanding scenarios, such as railway safety and national security.
