Experimental Characterization of Brillouin Scattering in an All-Solid Photonic Bandgap Fiber for Sensing Application

摘要

This paper gives an experimental study on Brillouin scattering property in an all solid photonics bandgap fiber (AS-PBGF) using tapering technique. There are four Brillouin resonance peaks, one from the pure silica core and three from microstructure cladding of the AS-PBGF. We report Brillouin frequency shift and linewidth of the fiber. Because these four peaks show the different temperature and strain dependence, the simultaneous measurement of temperature and strain can be achieved.
