Experimental observation of the ORRW.
(a,b) Temporal profiles of power in the U and V polarization modes at the fiber input (red solid traces). (c,d) Power spectra at the fiber input. (e,f) Output intensities after 3 km of optical fiber. (g,h) Power spectra at the fiber output. Solid black lines represent the analytical dark rogue wave solution.
