Short-cavity 1.55 /spl mu/m DBR lasers integrated with high-speed EAM modulators

Short-cavity InGaAsP/InP DBR lasers with integrated EAMs were designed and fabricated using a quantum well intermixing processing platform. RF bandwidths up to 25 GHz were achieved and open eyes at 10 Gbit/s observed with >10 dB dynamic extinction.
