Use Piezoelectric Bimorph for the Fiber Bragg Grating Tuner
A wavelength tunable optical filter based on a fiber Bragg grating using piezoelectric bimorph is realized in this paper, and the tuning condition is theoretically and experimentally analyzed. The Bragg central wavelength of the filter can be easily tuned adopting to a DC voltage. The maximum strain of the central wavelength depends upon the maximum operating voltage, and the tuning range efficiency was as high as 1.2pm/V, the reflectivity, shape and the reflective spectrums of the fiber Bragg grating central wavelength almost keep unchanged before and after tunning. This paper provides a reference for optical fiber Bragg grating tuner.with high efficiency.
