Abstract

Long-period fiber gratings are promising components as gain equalizers for erbium-doped fiber amplifiers, band rejection filters and sensors. It has been reported that these devices have a high temperature sensitivity, typically 0.05 nm/°C at room temperature. Judkins et al., showed a method to eliminate the temperature sensitivity by optimizing the refractive-index profile of the host fiber. In this paper, we show a novel method to compensate the temperature sensitivity using a boron codoped germanosilicate core fiber as a host fiber
