| Summary: | 碩士 === 國立臺灣師範大學 === 光電科技研究所 === 95 === In this thesis, we propose a fiber ring harmonic mode-locked fiber laser and detuning modulation frequency. We generate amplitude modulation by exciting outside RF modulation signal. In case of producing high speed pulse train signal, we also drive SOA in the fiber ring cavity system to stable the output high speed pulse train. Then we also generate phase modulation by exciting outside RF signal to make the phase longitudinal modes locking. At the last, we utilize polarization shift keying technique to produce high speed pulse train in the fiber ring cavity system.
In this fiber ring cavity system, we use three different kinds component to produce high speed pulse train and detuning the RF modulation frequency to analyze the repetition rate, RMS jitter, and rise time, respectively.
