Abstract :
The design of high bandwidth high efficiency 2 section MQW DFB lasers has been performed. 18 GHz FM bandwidth DFB lasers with FM efficiency of 1.5 GHz/mA are successfully achieved, which represents to our knowledge the highest FM efficiency compatible with >10 Gbit/s high-speed modulation rate reported for 1.5 μm DFB lasers
