NOVEL VCSEL DESIGNS TO ENABLE HIGH-PERFORMANCE OPTICAL TRANSMISSION OF DIGITAL DATA Vertical-cavity surface-emitting lasers (VCSELs) are the semiconductor laser workhorse of short-distance optical interconnects in data centers, server clusters, the Internet infrastructure, and supercomputer applications. However, as bandwidth demand increases and data centers grow larger, the optical interconnects will need to achieve high bandwidth over longer fiber-optic transmission distances, requiring VCSELs with narrow spectral width, sufficient output power, and higher modulation efficiency.
