Abstract :
In this paper, we propose a versatile and compact mechanism for tunable grating dispersion. A segmented piezoelectric stack with individually controlled segments was used to control the local strain at 21 positions along the grating. By step-wise monotonic increase or decrease of the strain along the grating a group-delay response close to that of a perfectly linearly chirped fiber Bragg grating (FBG) was obtained
