Abstract
Guided acoustic waves Brillouin scattering (GAWBS) was recently shown to facilitate chemical sensing outside the cladding of an unmodified fiber, even though the guided light wave never reaches the infstance under test. In this work, the study of GAWBS is extended to commercially-available, multi-core fibers. We show that GAWBS leads to inter-core cross-phase modulation, between cores that are otherwise optically isolated from one another. The observed modulation spectrum is in excellent agreement with the predictions of an opto-mechanical analysis of the fiber. Use of multi-core fibers would improve the signal-to-noise ratio in GAWBS-based sensors, and may enable distributed analysis.
