Experimental generation of optical flaticon pulses

International audience; We experimentally investigate the nonlinear reshaping of a continuous wave which leads to chirp-free and flat-top intense pulses or flaticons exhibiting strong temporal oscillations at their edges and a stable self-similar expansion upon propagation of their central region. This study was performed in the normal dispersion regime of a non-zero dispersion-shifted fiber and involved a sinusoidal phase modulation of the continuous wave. Our fiber optics experiment is analogous to considering the collision between oppositely directed currents near the beach, and it may open the way to new investigations in the field of hydrodynamics.

Akhmediev breathers as ultra-wideband pulses

We analytically calculate and discuss the radio-frequency spectrum of the so called Akhmediev breathers (ABs), a class of nonlinear solutions of the nonlinear Schrodinger equation that governs the propagation in a single mode optical fiber. We propose a practical application of ABs to the field of ultra-wideband pulse generation. © 2014 Wiley Periodicals, Inc. Microwave Opt Technol Lett 56:664–667, 2014

Émergence de flaticons dans les fibres optiques

Conférence pouvant être vue sur http://youtu.be/p9OnhcHQ3Mw; National audience; Nous étudions expérimentalement la propagation non-linéaire d'une onde continue menant à l'émergence d'impulsions au sommet plat et sans dérive de fréquence. Ces impulsions, appelées flaticons, subissent une évolution auto-similaire de leur partie centrale et présentent des oscillations temporelles marquées dans leurs flancs.
