Wavelength Conversion With 2r-regeneration By Ul-soa Induced Chirp Filtering

Simulations of ultra-long (10 mm) semiconductor optical amplifier's induced optical chirp (cross-phase modulation), with posterior conversion to amplitude modulation by proper filtering, show promising results for wavelength conversion with pulse re-amplifying and re-shaping in 10 Gbps and 20 Gbps. The dependences on filter bandwidth and optical input power (high, medium and low levels) are analyzed for conversion of originally clean and dirty eye-diagrams at the input gate within their reshaping capability. © Springer-Verlag 2004.3124304311Stubkjaer, K., Semiconductor Optical Amplifier-based All-Optical Gates for High-Speed Optical Processing (2000) IEEE J.
