In this paper we will discuss recent results on high speed VCSELs targeted for the emerging 16GFC (Fibre Channel)
standard as well as the now forming 25Gbps PCI express standard. Significant challenges in designing for reliability and
speed have been overcome to demonstrate VCSELs with bandwidth in excess of 20Gbps.
In this paper we describe progress in moving VCSELs toward production-ready status in several applications, among
others including substantially higher modulation speeds (14-25 Gbps, or even higher) than in current production. In
addition we describe potential VCSEL failure mechanisms not previously published, as well as the limitations of some
reliability testing techniques.
