Abstract :
A novel structure electroabsorption modulator/DFB laser integrated device is proposed and demonstrated. Both functional devices consist of InGaAs/InGaAsP MQW structures with different quantum energy levels, which are automatically formed in the same MOCVD run by using a selective area growth technique. A fundamental modulation with a 12.6 dB extinction ratio is demonstrated.
