Characterization and simulation of optical sensors.

Numerical simulation is gradually becoming an advantage in active safety. This is why the development of realistic numerical models enabling to substitute real truth by simulated truth is primordial. In order to provide an accurate and cost effective solution to simulate real optical sensor behavior, the software Pro-SiVIC™ has been developed.

Experimental chaotic map generated by picosecond laser pulse-seeded electro-optic nonlinear delay dynamics.

We describe experimental studies of the dynamical behavior of a recently proposed electro-optic discrete time nonlinear delay oscillator. With appropriate choice of the oscillator loop parameters and external forcing of the dynamics using a pulsed laser source, the system allows for the physical realization of a high dimensional mathematical nonlinear mapping. The dynamical features observed with this new class of discrete time delay oscillator differ significantly from those observed with similar continuous time nonlinear delay feedback oscillators and reveal the intrinsic discrete time nature of the dynamics.

Vibrating soliton pairs in a mode-locked laser cavity.

We show numerically the existence of vibrating soliton pairs that are consistent with observations performed with a passively mode-locked fiber laser. These vibrating pairs are new types of multisoliton complexes that exist in the vicinity of the phase-locked soliton pairs discovered a few years ago [Opt. Lett.

Bifurcations and multiple-period soliton pulsations in a passively mode-locked fiber laser.

We observed, numerically and experimentally, multiple-period pulsations of the soliton parameters in a passively mode-locked fiber laser. Pulsation periods can vary from a few to hundreds of round trips. Short and long period pulsations can appear in combination.
