Passively mode-locked fiber laser [PDF]
, 2019 172 p. Passive mode-locking is the routine technique to generate ultra-short optical pulses with fs~ps pulse width. As fiber lasers have the advantages of low cost and good robustness, they become attractive supplements of traditional solid state lasers. Hence, the investigation on the passively mode-locked fiber laser is of strong motivation.

Advanced Materials Technologies, EarlyView.Transducers convert physical signals into electrical and optical representations, yet each mechanism is bounded by intrinsic trade‐offs across bandwidth, sensitivity, speed, and energy. This review maps transduction mechanisms across physical scale and frequency, showing how heterogeneous integration and multiphysics co‐design transform isolated ...
