Development of high-speed VCSELs: 10 Gb/s serial links and beyond

In this paper we summarize production data from serial 10 Gb/s devices and report on 850 nm VCSEL arrays with channel speeds up to 25 Gb/s. The production data demonstrates that robustness of the basic technology as well as its suitability for cost effective, high volume production. The >10 Gb/s measurements on two dimensional arrays show that 850 nm VCSEL technology can be extended well beyond the 10 Gb/s links currently beginning to be deployed by volume field users.
