“…Further cost savings can be achieved by integrating multiple channels using a single-chip SOA array [9] for downstream-link deployment. The simplicity and effectiveness of using the SOA for simultaneous noise suppression, modulation, and amplification, renders it an attractive choice for cost-sensitive spectrum slicing applications.…”

“…Previous studies [9] have demonstrated the feasibility of this approach by using a saturated SOA to modulate a 0.6-nm spectrum slice at 600 Mb/s, yielding a lower error floor than an EOM without noise suppression. However, to the authors' knowledge, the noise suppression offered by a modulated SOA has not been previously compared with the noise performance in CW operation.…”

“…This technique is more compact than the bandwidth expansion using dispersionshifted fiber and offers additional benefits in that the SOA can be used simultaneously for both signal modulation and amplification [9], [10]. The SOA efficiently suppresses the intensity fluctuations in the input light across a bandwidth determined by the device operating point and carrier lifetime, and can be used with channel bit rates as high as several gigabits per second.…”

Abstract-In this paper, we present an experimental and numerical study of semiconductor optical amplifier (SOA)-based noise suppression and its relevance to high-channel-density spectrumsliced wavelength-division-multiplexed systems. We show that the improvement in signal quality is accompanied by spectral distortion, which renders it susceptible to deterioration in the presence of subsequent optical filtering. This phenomenon originates from the loss of intensity correlation between spectral components of the SOA output when the signal spectrum is altered. As a consequence, a design tradeoff is introduced between intensity noise and crosstalk in high-channel-density systems. These adverse effects can be overcome by optimized SOA design, resulting in a significant improvement in signal quality.Index Terms-Optical noise, semiconductor optical amplifier (SOA), spectrum slicing, wavelength-division multiplexing(WDM).

Abstract-A novel technique for the amplification and the compression of an optical pulse is proposed. Based on cascaded a semiconductor optical amplifier (SOA) and a nonlinear optical loop mirror (NOLM), the chirping effect induced by the SOA and the cross phase modulation effect between the signal pulse and control pulse can be utilized to shape the pulse. The picosecond pulse amplification and compression are demonstrated in this paper. A good theoretical model is designed with optimal parameters. Results show that the output signal pulse with high peak power, narrow pulse width, and low pedestal can be obtained using the designed model, which is suited for furture 640 Gbps optical communications. 128Wu, Tian, and Bao
