Improving signal quality in a spectrum-sliced WDM system using SOA-based noise reduction
Improving signal quality in a spectrum-sliced WDM system using SOA-based noise reduction
We present an experimental and numerical study into the filtering effects in a spectrum-sliced incoherent light system incorporating a semiconductor optical amplifier (SOA) for noise reduction. Techniques to reduce the signal degradation caused by post-SOA filtering are investigated. The alignment of the receiver/demultiplexer filter relative to the input spectrum-slice is demonstrated to have a noticeable impact on the received signal quality. We also show that the linewidth enhancement factor a of the SOA has a marked effect on the observed spectral distortion, which results in a strong dependence of the received signal quality on a. Our results illustrate the potential to improve system performance by optimized SOA design.

Abstract
We present an experimental and numerical study into the filtering effects in a spectrum-sliced incoherent light system incorporating a semiconductor optical amplifier (SOA) for noise reduction. Techniques to reduce the signal degradation caused by post-SOA filtering are investigated. The alignment of the receiver/demultiplexer filter relative to the input spectrum-slice is demonstrated to have a noticeable impact on the received signal quality. We also show that the linewidth enhancement factor a of the SOA has a marked effect on the observed spectral distortion, which results in a strong dependence of the received signal quality on a. Our results illustrate the potential to improve system performance by optimized SOA design.
