▲ [21p-221B-2] [INVITED] Ultra-Stable and Ultralow-Noise Mode-Locked Fiber Lasers
キーワード：Mode-locked fiber lasers, Low noise, High stability
Lower-noise and higher-stability mode-locked lasers and frequency combs are becoming more important and useful sources for a variety of applications ranging from precision spectroscopy to photonic signal generation and processing. In particular, all-fiber-based sources have clear advantages such as low cost, alignment-free operation, lightweight, and long-term stability. In this talk, I will overview our recent progress in realizing ultra-stable and ultra-low-noise mode-locked fiber laser sources. By combining an ultralow-noise mode-locked fiber laser and an ultra-stable fiber-delay-based timing reference, we have demonstrated an all-fiber photonic signal generator that emits ultra-low-noise optical pulse trains and microwave signals. With its simple implementation and robust operation, this source may find more widespread applications outside laboratory environment such as timing and synchronization, microwave generation, photonic radars, analog-to-digital conversion, and time-of-flight sensing, to name a few.
