Abstract

Short-cavity, 980 nm distributed Bragg reflector (DBR) lasers with integrated electroabsorption modulators (EAMs) were designed and fabricated using a quantum-well intermixing (QWI) processing platform. Design curves are discussed and the QWI fabrication details are presented. The transmitters exhibited RF bandwidths of 20 GHz and demonstrated error-free operation at 10 Gb/s.
