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

الملخص EN

Progress of high-speed vertical cavity surface emitting lasers (VCSEL) operating around 980 nm is reviewed.

A special focus is on their applications for future short-reach optical interconnects, for example, in high-performance computers (HPC).

The wavelength of 980 nm has fundamental advantages for these applications and plays a significant role in VCSEL research today.

The present data rates of 980 nm VCSELs exceed 40 Gbit/s, and excellent temperature stability has been reported.

The major concepts leading to these impressive developments are presented.
