Abstract

A new single-mode optical fiber with two Brillouin gain peaks is designed and fabricated to increase the differences in the temperature and strain coefficients between the peaks. The gains of the two Brillouin peaks are at a similar level and the temperature coefficient difference is ~0.2 MHz/°C. The fiber is well suited for simultaneous temperature and strain measurement with reduced uncertainties in Brillouin distributed fiber sensing applications.
