The effect of transverse strain on a uniquely etched phase-shifted fiber Bragg grating (FBG) was investigated. The relevant phase-shifted FBG was fabricated by the application of a non-uniform wet chemical etching technique. The prospect of providing temperature independent transverse strain measurements is also explored using this FBG.
