TLDR
A compact and stable all-fiber fundamentally mode-locked 12 GHz laser system that consists of a semiconductor-based saturable absorber with high modulation depth and a high gain per unit length, polarization-maintaining 0.8 cm long Er/Yb phosphate fiber as a gain medium is developed.Abstract:
We have developed a compact and stable all-fiber fundamentally mode-locked 12 GHz laser system. The passively mode-locked laser centered at 1535 nm has temporal pulse width of ∼2 ps and average power of 5 mW. The timing jitter, which is cumulative from pulse-to-pulse, has been measured using an optical cross-correlation method and found to be 44 fs/pulse. The self-starting, mode-locked laser consists of a semiconductor-based saturable absorber with high modulation depth and a high gain per unit length, polarization-maintaining 0.8 cm long Er/Yb phosphate fiber as a gain medium.read more

5 GHz fundamental repetition rate, wavelength tunable, all-fiber passively mode-locked Yb-fiber laser.
TL;DR: The long-term stability of the mode-locked operation in the ultrashort laser cavity is realized by exploiting temperature controls and this is, to the best of the authors' knowledge, the highest fundamental pulse repetition rate for 1-μm mode- Locked fiber lasers.

High-repetition-rate ultrafast fiber lasers.
TL;DR: A new method for tuning wavelength and repetition rate is proposed and demonstrated for a femtosecond fiber laser at the wavelength of 1.5 µm and the value of integrated timing jitter gradually increases with an increase in temperature.

Microwave photonics combines two worlds
José Capmany,Dalma Novak +1 more
TL;DR: Microwave photonics has attracted great interest from both the research community and the commercial sector over the past 30 years and is set to have a bright future as mentioned in this paper, which makes it possible to have functions in microwave systems that are complex or even not directly possible in the radiofrequency domain and also creates new opportunities for telecommunication networks.
