Dynamic properties of 1.5 μm quantum dash lasers on (100) InP

摘要

The static and dynamic properties of state-of-the-art InP-based QDash lasers around 1.55 μm are reported. Demonstrated are ridge waveguide lasers with a total output power of 37 mW and a total slope efficiency of 0.40 W/A that show a 3 dB modulation bandwidth of 8.0 GHz and a modulation efficiency of 0.76 GHz/(mA)~(1/2) in continuous-wave operation.
