Optics as a key to understanding rogue waves

Rogue waves are powerful waves that erupt suddenly. They are rare, but destructive. Above all, they are unpredictable. Surprisingly, researchers have been able to better understand these fascinating waves by studying similar phenomena in fiber optic lasers.   Before scientists began measuring and observing them, rogue waves had long been perceived as legends. They can […]
