Abstract :
In this paper, we demonstrate an all-fiber pulse-shaping system that can generate shape-controllable pulses with a short rise time and high resolution by adjusting variable optical attenuators of the 64 fiber channels independently. A 6.4 ns arbitrarily shaped pulse with less than 0.1 dB shaping precision is obtained by stacking 150 ps chirped subpulse of 1053 nm. The linewidth of pulse is 1.2 nm and the dynamic range operating at 1 Hz rate is more than 40 dB.
