All-Optical Wavelength Conversion With Large Wavelength Hopping by Utilizing Multistage Cascaded SOA-Based Wavelength Converters

摘要

A novel broadband wavelength converter by multistage cascaded semiconductor optical amplifier (SOA)-based wavelength converters is proposed. We have demonstrated, for the first time, broadband wavelength conversion in the wavelength range of 1320-1610 nm by using three-stage cascaded SOA-based wavelength converters with each different gain band.
