Operation of 1550-nm electroabsorption-Modulated laser at 40 degree C for 10-gb/s, 40-km transmission

Semicooled operation at 40 degree 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 cha...

Description
Summary:	Semicooled operation at 40 degree 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 degree C. Good eye pattern and near zero chirp with the average power over 0 dBm are obtained at 40 degree C, with an estimated lifetime over 20 years.
