Abstract
The characteristics of a frequency-modulated (FM) actively mode-locked fiber optical parametric oscillator have been demonstrated experimentally. In particular, the effects of pump power and modulation frequency on the features of the generated pulses (e.g., output power, RMS timing jitter, pulse width, and time-bandwidth product) are analyzed. Moreover, a stable pulse train of 37 ps with a RMS timing jitter of around 2.51 ps and a repetition rate of 10 GHz are generated. The results show that pulse trains with narrow pulse width and low RMS timing jitter are achievable when the modulation frequency increases. The corresponding time-bandwidth products at different pump powers are 0.61–0.66. In addition, stable optical pulses at 1567.38, 1551.92, 1544.29, and 1536.73 nm are generated simultaneously based on multiple four-wave mixing processes.
