摘要：

A long-period fiber grating sensor induced by electric-arc discharge has been fabricated and demonstrated for the simultaneous measurement of temperature and strain. The proposed sensor was fabricated by inscribing a sing-mode fiber with periodic electric-arc discharge technology that was produced from a commercial fusion splicer. The resonance dips formed by the coupling between cladding modes and core mode have different sensitivity responses, so the simultaneous measurement for multiple parameters was realized by monitoring the wavelength shifts of the resonance dips. Because of the easy fabrication and low cost, the sensor is promising for applications for which simultaneous measurement of temperature and strain is required.
