Abstract :
The fabrication and performance of 1.3 ¿m InGaAsP buried crescent lasers with semi-insulating Fe-doped InP current blocking layers grown by MOVPE are reported. A modulation bandwidth above 8.3GHz has been achieved at room temperature without using a mesa-stripe geometry. CW output power up to 30 mW per facet at 20°C and CW operation up to 95°C have been obtained. The semi-insulating InP layer alone is proved to be an effective current blocking layer.
