Progress of high-speed vertical cavity surface emitting lasers (VCSEL) operating around 980nm is reviewed. A special focus\nis on their applications for future short-reach optical interconnects, for example, in high-performance computers (HPC). The\nwavelength of 980nm has fundamental advantages for these applications and plays a significant role in VCSEL research today. The\npresent data rates of 980nm VCSELs exceed 40 Gbit/s, and excellent temperature stability has been reported. The major concepts\nleading to these impressive developments are presented
