A Highly-Stable 59 GHz Soliton Source at 1550 nm

摘要

A higly-stable soliton source is demonstrated by compressing the sinusoidal modulation in the output of a short-cavity Er/Yb bulk phosphate-glass laser operating simultaneously at two frequencies. The 58.55 GHz modulation is converted into a train of 3.2ps pulses by means of soliton pulse compression in a comb-like dispersion-tailored fiber. By spectrum analysis of thedirect-detection photocurrent, the short-term stability of the repetition rate is shown to be 10 kHz.
