Abstract
We report for the first time, rogue waves generation in a mode-locked fiber laser that worked in multiple-soliton state in which hundreds of solitons occupied the whole laser cavity. Using real-time spatio-temporal intensity dynamics measurements, it is unveiled that nonlinear soliton collision accounts for the formation of rogue waves in this laser state. The nature of interactions between solitons are also discussed. Our observation may suggest similar formation mechanisms of rogue waves in other systems.
Highlights
Rogue waves (RWs) have drawn widespread interest in physics systems ranging from hydrodynamics to superfluidity [1]
We report for the first time that RWs can be generated in another modelocking state of a fiber laser, namely the multiple-soliton state in which a total number of ~400 solitons occupied the whole laser cavity
The optical spectrum of this stable soliton bunch is shown in Fig. 1(b); Kelly sidebands on the spectrum are characteristics of solitons [33]
Summary
Rogue waves (RWs) have drawn widespread interest in physics systems ranging from hydrodynamics to superfluidity [1]. They have extremely large amplitude and seem unpredictable. RWs were observed for the first time in supercontinuum generation in optical fibers [2] This subject has been extensively studied in different optics systems since [3], as these convenient optical experiments relate to giant waves in oceans and many other scientific fields [4]. Soliton bunch is a state in which many solitons bound into a group [13,14,15] This state provides the possibility to simplify the burst-mode amplifier systems [16,17]. Chaotic soliton bunch state can induce RWs resulting from interaction of solitons [5,8], but it is a challenge to identify experimentally how solitons interact mutually to generate RWs
