Gemini Fiber for Interferometry and Sensing Applications
Figure 8
(a) Bragg wavelength λ A and λ B measured for cores A and B when a piece of Gemini fiber G2 with FBGs is compressed (positive values of the displacement) and stretched (negative values) at , and . (b) Relative wavelength shift at three temperatures. The displacement is associated to wavelength and the temperature dependence is small.
