Long-term stable device for tuning fiber Bragg gratings

Abstract

It is demonstrated that with a proper choice of embedding material, the composite beam bending method constitutes an effective and reliable approach for tuning fiber Bragg gratings. A long-term stable device is presented with a dynamic range of $80\mathrm{nm}$, which exhibits insertion losses smaller than $0.28\mathrm{dB}$ and small variations of the full width at half-maximum.
