✦ Synopsis

The possibility to increase "signal/noise" ratio in optical time domain reflectometer supplied with the nonlinear absorber based on single-walled carbon nanotubes is shown. T, % 25 0 50 75 SNR Γ— 10 4 1 0 2 3 10 7 10 8

, W/cm 2 I A dependence of the absorber transmission T (black squares) and the "signal/noise" ratio SNR (red dots) on the incident laser intensity I. A straight line is the "signal/noise" ratio obtained without the nonlinear absorber
