In this work, we report a new fiber architecture providing high accuracy measurements of both residual chromatic dispersion and optical signal-to-noise ratio. Taking advantage of the nonlinear spectral evolution of pulses propagating in a Kerr medium, we have numerically and experimentally validated the use an anomalous dispersive fiber combined with a central spectral filtering.
We review our recent work in the field of optical rogue wave physics and applications. Beginning from a brief survey of the well-known noise and incoherence processes in optical fiber supercontinuum generation, we trace the links to recent developments in studying the emergence of high contrast localised breather structures in both spontaneous and induced nonlinear instabilities. In the latter case,...
We report the numerical and experimental studies of a spectrally filtered fiber-based optical limiter at 170 Gbit/s. The device, including less than 1 km-long of highly nonlinear optical fiber and a 3 nm-width filter, exhibits good performance at an average input power of 14.5 dBm. No power penalty has been observed and a strong robustness against optical noise has been demonstrated.
