Reconfigurable Optical Signal Processing Based on a Distributed Feedback Semiconductor Optical Amplifier

Reconfigurable Optical Signal Processing Based on a Distributed Feedback Semiconductor Optical Amplifier.

All-optical signal processing has been considered a solution to overcome the bandwidth and speed limitations imposed by conventional electronic-based systems. Over the last few years, an impressive range of all-optical signal processors have been proposed, but few of them come with reconfigurability, a feature highly needed for practical signal processing applications. Here we propose and exper...

Semiconductor-Optical-Amplifier Mach-Zehnder Interferometer Based Optical Networks

In this paper, an all-optical AND logic scheme which exploits the cross-phase modulation (XPM) effect in semiconductor-optical-amplifier-assisted Mach-Zehnder Interferometer (SOA-MZI), is proposed, performance analyzed and parameters optimized. The proposal is validated and the system performance under various parameters is examined through numerical simulations. With only moderate parameters, ...

Self-Equalized Distributed Amplifier for Wide Band Optical Transceivers

A novel technique for a self-equalized distributed amplifier is presented by showing the analogy between transversal filters and distributed amplifier topologies. The appropriate delay and gain coefficients of amplifier circuit are obtained by a Fourier expansion of the raised cosine spectrum in the frequency range of 0-40GHz.

All Optical Parametric Frequency Conversion Based on Cross Gain Modulation on a Reflective Semiconductor Optical Amplifier

This paper reports a detailed experimental study of the wavelength conversion dynamics using cross-gain modulation in reflective semiconductor optical amplifiers. The effect of pump and probe powers on the operating performance in terms of signal to noise ratio was experimentally investigating. The variation of others performance indicators such as extinction ratio, timing jitter and eye openin...
