Abstract
We have demonstrated suppression of low-frequency fluctuations of backscattered Rayleigh radiation in distributed fiber optical sensors with chaotic single-longitudinal mode DFB and multi-longitudinal mode FP lasers subjected by incoherent optical feedback. Significant decreasing of Rayleigh power variations up to 15-20 dB for 10-1000 Hz frequency interval was recorded for both chaotic lasers. It was shown that chaotic DFB laser also efficiently restrain stimulated Brillouin scattering in the test fiber. The results have important consequences for distributed fiber optical sensors, which utilized Rayleigh signals.
