Abstract
A method of stabilizing a fiber Bragg grating (FBG) disposed in a thermomechanical housing included performing an initialization process including measuring a transmission ratio at a plurality of FBG temperatures between an initial and final temperature, determining a maximum transmission ratio, and changing the temperature of the FBG until the transmission ratio equals a target transmission ratio. The method also includes performing an operation process including (a) measuring the transmission ratio, (b) adjusting the FBG temperature to align the measured transmission ratio with the predetermined fraction of the maximum transmission ratio, and (c) iteratively performing (a) and (b).
