In this paper, we present the design and manufacturing of next-generation 850 nm 10 Gb/s vertical-cavity
surface-emitting lasers (GenX VCSELs). They were developed to provide a 10 Gb/s solution that meets
Class-1 eye safety limits, IEEE 802.3ae standards, 10G Fiber Channel standards, and corresponding multisource
agreement requirements for emerging low-cost, high-volume, and high-performance data
communication applications in local and storage area networks (LANs and SANs). The paper covers GenX
device designs, manufacturing processes, DC and AC characteristics, equivalent circuit models,
recommended operating conditions, as well as reliability studies. As a simple drop-in replacement, we
have successfully demonstrated that GenX VCSELs work well with all existing Emcore 10G transmitter
optical sub-assembly (TOSA) products.
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 100°C 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.
