Abstract

In this paper, we have investigated cryogenic temperature response of long-period fiber gratings (LPFGs) inscribed on standard photosensitive single-mode fibers without any polymeric coatings. The resonance wavelength of the fabricated LPFG, which was ~1530.778 nm at room temperature (296 K), was monitored under various temperatures ranging from 77 K to 296 K. The temperature sensitivity of the resonance wavelength was measured as ~402.4 pm/K, and the adjusted R-square value of the linear fit of the temperature response curve was evaluated as 0.98144.
