A novel scheme of all-optical pattern free 2R regeneration is demonstrated through monolithically integration of EAM and SOA. In comparison to Back-to-back case, a clearer 40Gb/s eye-diagram with 2dB improvement is obtained.
Low-pattern-dependence and chirp-control optical modulation using a monolithic integration of devices is proposed and demonstrated in this study. The monolithic integration consisting of semiconductor optical amplifier (SOA) and electroabsorption modulator (EAM) is used. As high enough optical power is coupled into a device to reach saturation condition, the field driving operation in an EAM (reversed-bias...
A low-pattern-dependent-and-chirp-compensated data transmission is demonstrated from monolithic integration of EAM and SOA. By reversed saturation behaviors between EAM and SOA, clear 10Gbit/s eye diagram with 0.6 GHz chirp-compensation and enhanced signal-to-noise ratio is realized.
Enhancement of quantum well intermixing (QWI) through sputtered SiO2 on InGaAs layer is demonstrated. From large thermal expansion coefficient, blue shift of 60nm improvement over InP junction, also verified by laser facbrication.
A novel low-pattern-dependence pre-chirp technology using EAM-integrated SOA is demonstrated. Reduction of 10Gb/s pattern dependence with chirp-compensation of 0.9GHz is realized by the inherently contrary saturation behaviors of EAM and SOA.
