Non Inverting and Non Filtered Wavelength Converter Based on an InAs/InP(100) QD Ring Laser at 1.55μm

A novel wavelength conversion concept based on InAs/InP(100) quantum-dot ring- laser structure is demonstrated requiring no external laser, optical inversion or optical filtering. Demonstration at 622 Mb/s for a 2 mm ring, suggests applicability for much higher speeds.
