Abstract: Based on the principles of various wavelength tuning techniques for fiber Bragg grating (FBG), a higher precision wavelength tuning method is proposed that is easy to realize and by which the interference caused by undetermined temperature is eliminated. The examples of the parameter design and the experimental procedure, as well as the application conditions are presented. The theoretical analyses and the experimental results have demonstrated that this new method for FBG tuning has the advantages of easy to operate and a wider range of wavelength shift with good repeatability.
