Vertical-Cavity Surface-Emitting Lasers Enable High-Density Ultra-High Bandwidth Optical Interconnects

Vertical-Cavity Surface-Emitting Lasers (VCSELs) are key components enabling power-and cost-efficient, high-density, ultra-high bandwidth parallel optical interconnects for data center and high-performance computing applications. This paper presents recent developments at TE Connectivity (TE) in the area of 25 Gb/s per channel-class VCSEL and optical transmitter technology for applications such as 100G and 400G Ethernet and Enhanced Data Rate InfiniBand pluggable and mid-board connectivity solutions.
