Abstract :
The effects of gain saturation due to amplified spontaneous emission in systems comprising cascaded semiconductor laser amplifiers and attenuators are investigated. The influence of the relative spatial distribution in the link of gain and loss is analyzed numerically, and conclusions regarding noise optimal structures are drawn. It is shown that the performance of links with gain saturation can be quite different from the ideal, unsaturated case.<>
