Abstract

High-frequency guided acoustic Brillouin modes have recently been
observed in small-core silica photonic crystal fibers. In this paper, we
investigate the temperature dependence of the optical sideband frequency
generated by one of these guided acoustic waves. The experimental
results show a temperature coefficient of 100 kHz/degrees C at an
acoustic resonance frequency of 1.15GHz and are in very good agreement
with the theoretical predictions. This coefficient demonstrates a
temperature sensitivity 10 times larger than that previously reported in
conventional single-mode fibers, which is promising in view of potential
applications to optical fiber sensors. (C) 2011 Optical Society of
