Mapping the Uniformity of Optical Microwires Using  Phase-Correlation Brillouin Distributed Measurements 

The  distributed  Brillouin  gain  profile  of  an  ultrathin  optical  microwire  made  of chalcogenide-glass  is  characterized  using  a  phase-modulated  correlation-domain  measurement
technique. Method resolves variations of uniformity below 5% along a 13 cm-long microwire.
