We experimentally demonstrate a scheme for reshaping 40 Gb/s packets that is wavelength-preserving. The scheme, based on cross-gain-compression in an SOA, is polarization-independent and does not suffer from any transient effect at packet edges.
Analysis and detailed simulations show the operational equivalence of two semiconductor optical amplifier (SOA) assisted self-nonlinear switches, namely the nonlinear polarization switch (NPS) and the SOA-Mach-Zehnder Interferometers (SOA-MZI). Under proper conditions, both switches, although physically different, have similar functional features, such as the power transfer characteristics, the gain...
We experimentally characterized at 10 and 40 Gb/s the optical packet power equalization capability of the non-linear polarization-rotation effect in an SOA. We found at 40 Gb/s a maximum input dynamic range tolerance of 12 dB.
We report a detailed experimental characterization of the wavelength conversion of 10 Gb/s non-return-to-zero differential phase shift keying (NRZ-DPSK) optical signals based on four wave mixing (FWM) in a semiconductor optical amplifier (SOA). The performance of this coherent wavelength converter is compared with theoretical results and found to perform better, in terms of extended range of signal-to-pump...
