The sensitivity of Brillouin frequency shift to strain and temperature has been studied in a low-bend loss silica fiber, at two different wavelengths (850 and 1550 nm). The results show that the ratio between strain sensitivity at the two wavelengths is different from the ratio between temperature sensitivity, which can be conveniently used for simultaneous… CONTINUE READING
