All-Optical Signal Processing with Semiconductor Optical Amplifiers and Tunable Filters

All-optical signal processing functions are key enabling technologies for signal regeneration and switching in next generation optical networks. SOA has been receiving much attention in all-optical signal processing for its various nonlinear effects and potential to be integrated, and it has been exploited to realize all-kinds of signal processing functions such as all-optical wavelength conversion, all-optical logic operation, all-optical 3R regeneration, all-optical pattern conversion, all-optical sampling, all-optical demultiplexing, etc. In this chapter, all-optical signal processing based on SOAs and filters was experimental and theoretical investigated. Complicated theoretical model for SOAs is presented, in which besides those conventional effects such as XGM and XPM related to interband recombination process, those ultrafast nonlinear effects such as carrier heating, spectral hole.
