50GHz optical pulse generation for synchronization of high-speed computing signals

High-speed optical synchronization signal generation high speed computer is very important. The rational harmonic (RH) modelocking scheme is a useful technology to generate pulses at a repetition rate higher than the modulation frequency. In this paper, we design an amplitude modulated mode-locked figure eight fiber laser as a 50 GHz optical pulse. In the cavity of high speed laser source, we utilize an amplitude modulator and phase modulator to inject additive modulation signal respectively. The modulation signal can let the longitudinal mode in cavity produce constructive interference, and then, achieve small modulation signal to excite harmonic and rational mode-locked laser in high repetition rate. The pulsewidth is 13.1ps with feeding a 16.4dBm, 12.5002248GHz modulation signal to the amplitude modulator. The pulsewidth, rise time and falling time of the 50GHz optical pulse are adjustable under experimental verification. In optical transmission systems, we consider the 50GHz optical pulse used in the optical interconnection transmission analysis.
