Abstract :
In summary, we have demonstrated high performance 850 nm GaAs DBR QW VCSELs on p-type substrates with low series resistance of 17 ohms for 22 /spl mu/m implant diameters. The current spreading can be reduced by optimizing the doping profile above the active region. Both n-side-up and p-side-up VCSELs show comparable speed response of 1.5 Gbps.
