Outline of Final Research Achievements

An optical sampling technique using the nonlinear optical loop mirror (NOLM) has been suggested. By inducing a nonlinear fiber phenomenon of pulse trapping in the NOLM, a femto-second pulse is extracted from an input pico-second pulse. In the experiment, the NOLM consists of polarization maintaining fiber devices. The input-output characteristics have been analyzed both experimentally and numerically. A 3.6 ps pulse waveform was reconstructed by using the optical sampling technique. The NOLM using the pulse trapping phenomenon is useful for the ultrafast all-optical control technique.
