Analysis of Bandwidth-reduced Local Oscillator in Brillouin Optical Time Domain Reflectometry

摘要：

A local oscillator for coherent detection of Brillouin scattering in Brillouin optical time domain reflectometry (BOTDR) has been analyzed. A ring Brillouin fiber laser is used as local oscillator, and the Brillouin gain media is 1060nm single mode fiber. The detected frequency is reduced from ~11GHz to ~420MHz. Influence of self-lasing cavity-modes on BOTDR is analyzed, imposing “burr intervalled at 2.5MHz on the frequency domain analysis, and supressed by increasing the cavity loss.
