Abstract :
Semicooled operation at 40°C of electroabsorptive modulator integrated laser (EML) for intermediate reach communication has been demonstrated. Reproducible operation at the elevated temperature was achieved through a device parameter optimized based on the temperature dependence of the dc characteristics of EML and a design of multi-quantum-well structure providing both relevant output power and high-frequency bandwidth at 40°C. Good eye pattern and near zero chirp with the average power over 0 dBm are obtained at 40°C, with an estimated lifetime over 20 years.
