Graphene oxide/PVA film is used as saturable absorber for mode locking erbium-doped fiber laser and ytterbium-doped fiber laser. It provides modulation depths of 2.6% and 6% at 1.06 mu m and 1.55 mu m, respectively. Stable mode-locked pulses are obtained for both lasers confirming that graphene oxide is cost- effective for 1.06-mu m and 1.55-mu m pulse generations.

Stable optical clocks are obtained from 1.3-mu m and 1.5-mu m SOA-based fiber lasers using passive technology. The waveforms depend on SOA currents, and the repetition rates can be tuned by varying the relative length of sub-cavities.

Stable optical pulse trains are obtained from 1.3-mu m and 1.5-mu m semiconductor optical amplifier (SOA)-based fiber lasers using passive optical technology. The waveforms depend on SOA currents, and the repetition rates can be tuned by varying the relative length of sub-cavities. The output pulse trains of these SOA-based fiber lasers are stable against intracavity polarization adjustment and environmental perturbation. The optical clock generation is explained in terms of mode competition, self-synchronization, and SOA saturation. Without resorting to any active modulation circuits or devices, the technology used here is simple and may find various applications in the future. (C) 2015 Optical Society of America
