Subpicosecond-time-domain reflectometry.
We demonstrate a new method of optical time-domain reflectometry using subpicosecond pulses and nonlinear detection. The high-spatial-resolution ( approximately 15-microm) temporal resolution and sensitivity put new limits on the size and nature of defects that can be detected, localized, and analyzed in optical fibers.
