Abstract (EN): A passive self-referencing all-fibre technique for Bragg wavelength detection using a biconical fibre filter is described. This filter, basically a tapered depressed-cladding fibre, exhibits a periodic spectral power dependence which permits direct tracking of wavelength shifts in a 20nm unambiguous range. Dynamic strain resolution of 1.5 mu strain/root Hz has been achieved.
