VCSELs for high-speed data communication in TO packages: pushing the envelope

In this paper we report the results from on-going performance enhancements of Emcore's comprehensive line of data communication VCSEL products in cost effective hermetic TO packages. Data are presented on the -20 to 100dC temperature range operational characteristics of our offerings at 1.25, 2.5, 4, and 10 Gb/s. The discussion covers high-speed parameters, fiber coupling efficiency, and other important features of the packaged devices.
