11 May 2007 High resolution OTDR based on up-conversion photon-counting module
Author Affiliations +
We implement an OTDR with photon-counting modules at 1550nm based on sum frequency generation in a PPLN waveguide. The narrow temporal response of those detectors allows achieving a 2-points resolution of few centimetres.
