Progress on High-Speed 980 nm VCSELs for Short-Reach Optical Interconnects

<table>A scanning microscope image of a fabricated 980 nm VCSEL with the active region grown in the submonolayer growth mode. The smaller top mesa with the ring contact and a part of the contact pads in the ground-signal-ground configuration are demonstrated in the picture; also the shape of the larger bottom mesa can be identified.</table>
