✦ Synopsis

Reflections of sound from waveguide terminations can play a major role in the performance of a random noise active attenuator. Their influence depends on the direction reflections propagate along the waveguide and on the configuration of the attenuator. Upstream and downstream reflections are therefore important parameters to be considered when choosing the configuration best suited for a particular application. Theoretical and experimental results are presented, showing that waveguide reflections interact with other major parameters of a random noise attenuator.

## Abstract The influence of the ASE noise on the cascadability of SOA‐MZI structures is investigated. The experimental results show that saturation effects in the SOAs are the main cause of signal degradation, so counter‐propagation pump schemes as well as lower bias currents and optical powers ar
