Effects of well number on temperature characteristics in 1.3-/spl mu/m AlGaInAs/InP quantum well lasers

Effects of well number on temperature characteristics have been investigated in 1.3-/spl mu/m AlGaInAs-InP multiple-quantum-well (MQW) lasers. A record high pulsed operating temperature of 220/spl deg/C has been achieved in lasers with 10 QWs and a small power reduction of -1.68 dB between 20 and 80/spl deg/C has been obtained in lasers with 4 QWs.
