Abstract :
A 1.55 μm p-substrate laser with a very low threshold current of 1.7 mA and a high bandwidth of 14 GHz is demonstrated. This combination of low threshold current and high frequency response was accomplished by using strained quantum wells and semi-insulating blocking layers grown by hydride-VPE. The authors believe this is the first report on the combination of a low threshold current and a high frequency response for a p-substrate laser. This component will be useful in high speed parallel optical interconnects for future broadband systems
