| Abstract(in English) | In order to use internal phase of broad spectral components in ultrashort optical pulses for telecommunication applications, it is necessary to measure the internal phase of each pulse by a single-shot. We succeeded single-shot measurement of phase shift in a phase-modulated pulse train. For this measurement, we propose a new method combining spectral phase interferometry (SPI) and a streak camera. Using SPI, phase measurement is possible with a fixed delay time between the probe and reference pulses, and the streak camera can resolve the pulse train of femtosecond pulses in the time domain. As an example of pulse-to-pulse measurement in a random data train, we provided phase modulation to a particular pulse in the pulse train at 76 MHz by cross phase modulation, and successfully measured the nonlinear phase shift of the single pulse. |
