20 GHz all-optical clock recovery based on fibre laser mode-locking with a fibre nonlinear loop mirror as variable intensity/phase modulator

摘要

All-optical clock recovery is demonstrated at 20 Gbit/s with a fibre-based nonlinear loop mirror used as intracavity modulator in a mode-locked fibre laser. The effect of combining AM and FM modulation simultaneously is analysed theoretically and experimentally.
