We report the small-range strain characterization of anisotropic fiber Bragg gratings (FBGs) written by high-intensity femtosecond UV pulses. The FBGs are characterized with applied strain of 0-300 µe using a high-speed Czerny-Turner spectrometer. The strain response slope is comparable to typical FBGs. © 2008 IEEE.
