Abstract

1.3 μm uncooled AlGaInAs DFB-LDs with λ/4shifted grating have been successfully demonstrated. Relaxation oscillation frequency as high as 11.5 GHz has been obtained. Clear opening in the eye diagram under 10 Gbps direct modulation at 75°C has been also confirmed. Preliminary life test over 5000 hours with no failure indicates its excellent reliability. The 1.3 μm AlGaInAs DFB-LD with λ/4-shift grating is promising for the next generation high-speed data link systems such as 10 Gbps Ethernet.
