The advancement we achieved on the ultra-wide bandwidth optical sampling for high speed optical fiber communication systems was reviewed in this paper. In our optical sampling scheme, the double frequency optical under-sampling was proposed to realize the data rate adaptive measurement. The chirped Z-transform based on signal processing was proposed to improve the synchronization accuracy and speed...
A technique using artificial neural networks trained with parameters derived from reconstructed eye diagrams for optical performance monitoring in 40-Gbps optical duobinary (ODB) system is demonstrated. Firstly, the optical signal is asynchronously sampled by short pulse in the nonlinear medium such as semiconductor optical amplifier and highly nonlinear fiber, the sampled and collected data is then...
An optical sampling scheme based on nonlinear polarization rotation in a gain-transparent semiconductor optical amplifier is proposed. This scheme enjoys many advantages, which include simple configuration, absence of amplified spontaneous emission noise, absence of pattern effects, high speed of operation, high sensitivity, broad signal wavelength coverage and polarization-independence.
A new theoretical model is presented to describe polarization-dependent nonlinear gain in semiconductor optical amplifiers (SOAs) on subpicosecond timescales. Based on this model, the influences of nonlinear polarization rotation (NPR) on pulsed four-wave mixing (FWM) in SOA used for optical sampling are discussed. The numerical results are in good agreement with reported experimental measurements
