We present the first direct single-shot recordings of optical rogue waves by using a homemade Time Microscope having a temporal resolution of 250fs (P. Suret et al., Nature Communications 7, 13136 (2016)). In our experiments, partially coherent waves emitted by a amplified spontaneous emission light source experience nonlinear propagation in a single mode optical fibre. Experimental observation reveal the emergence of coherent structures embedded in the random waves. The probability density function of optical power is found to evolve from exponential distribution that corresponds to linear superposition of waves to heavy tailed distribution. The experiments are very well reproduced by numerical simulations of the one dimensional nonlinear Schrdiner Equation.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the conference proceedings. They include the speaker's narration along with a video recording of the presentation slides and animations. Many conference presentations also include full-text papers.
