| Outline of Final Research Achievements |
Based on the linear optical sampling, fine time resolution and high dynamic range impulse response measurement of optical fibers are realized, by using two independently oscillating pulse lasers as the signal and local pulse sources. By the method, it is possible to measure the impulse response of multimode fibers with a few picosecond resolution and 70 to 80 dB dynamic range. Since this method is useful for various length of optical fibers including installed cables, it would be promising as the technology for characterizing multimode fibers.
