High-efficiency and wideband SOA-based wavelength converters by using four-wave-mixing with orthogonal pumps and an assisted beam

摘要

Using a 1480-nm assisted beam significantly improves conversion efficiency and SBR for wideband SOA wavelength converters with orthogonal pumps. With a moderate-gain SOA, greater than -10 dB efficiency over 70-nm wavelength range is achieved.
