Abstract
A remote sensing system based on bandpass long-period fiber grating (LPFG) and fiber ring laser is proposed in this paper. The reflective bandpass LPFG is fabricated by fusion splicing a piece of hollow core fiber (HCF) to the LPFG. And the fiber ring laser is employed to narrow the line-width of the bandpass LPFG and realize remote sensing. As an application example, a temperature experiment is conducted at the spot more than 1 km away from the fiber ring laser. The experimental results show that such a sensor has a sensitivity of 0.0254nm/°C within the range of 20-150°C.
