This final technical report outlines the development of Vertical-Cavity Surface-Emitting Lasers VCSELs for use in high-speed parallel data links. During this contract, Optical Concepts has produced VCSELs with greatly improved performance, and has developed packaging technologies for VCSELs. VCSELs have been developed that operate at greater than 5 GHz with sub-milliamp threshold currents. With low turn on delays, these devices have demonstrated GHz data rates with no pre-bias. VCSEL arrays have been incorporated into high-speed, parallel, fiber coupled packages. Optical Concepts has demonstrated packages using both top and bottom emitting VCSELs, and has developed an integrated microlens technology to ease packaging tolerances.
