Abstract

In this work we demonstrate for the first time a monolithically integrated, widely tunable, electroabsorption modulator (EAM) based sampled grating DBR (SGDBR) laser transmitter fabricated in a novel dual quantum well (DQW) integration platform that breaks the fabrication and growth barriers associated with integrating quantum well EAMs with laser sources. Compared with the well established offset quantum well (OQW) tunable transmitters, the DQW devices require no additional processing or growth steps, and demonstrate significant improvements in bandwidth, modulation efficiency, insertion loss, and chirp characteristics.
