Low-operation-current and highly-reliable 1.3-/spl mu/m AlGaInAs strain compensated MQW-BH-DFB lasers for 100/spl deg/C, 10-Gb/s operation

A record-low 25.8-mA/sub p-p/ modulation current for 10-Gb/s modulation at 100/spl deg/C was demonstrated using AlGaInAs strain compensated MQW-BH-DFB lasers. A median life of more than 1/spl times/10/sup 5/ hours at 85/spl deg/C was estimated after an aging test of 4000 hours.
