Abstract
With a modulator based 10 GHz optical frequency comb generator at 1.55 mm, we report a 20 GHz repetitive train of optical pulses as short as 450 femtoseconds. The timing stability of the 20 GHz pulses, in addition to the power and phase for optical comb modes, shows a strong dependence on the relative frequency detuning between the comb generators cavity and the seed CW laser. With a new and simple scheme, the comb generator s cavity resonance was locked to a narrow-linewidth seed laser within an optical frequency range {less than or equal to} {approximately} 5 MHz, enabling high-fidelity 20 GHz sub-picosecond pulses and stable optical frequency comb generation for indefinite periods.Citation
