Measurement of Residual Chromatic Dispersion or OSNR via Nonlinear Spectral Evolution

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.
