Abstract
Abstract The thermal drift coefficient of the Bragg wavelength of fiber Bragg grating (FBG) is unacceptably high when the FBG is used as a wavelength reference or a wavelength‐selective passive component, especially in a dense wavelength division multiplexing (DWDM) system. A light, small and robust carbon fiber reinforced polymeric composite structure is proposed to compensate for the temperature induced wavelength drift in FBG. It has been shown to be able to reduce the temperature induced wavelength shift of a fiber Bragg grating from 10 pm/°C to below 1 pm/°C. Stability in long term performance over a two month period has also been demonstrated. A fabrication route that leads to optimal compensation performance has also been proposed.
