There is now a CONTENT FREEZE for Mercury while we switch to a new platform. It began on Friday, March 10 at 6pm and will end on Wednesday, March 15 at noon. No new content can be created during this time, but all material in the system as of the beginning of the freeze will be migrated to the new platform, including users and groups. Functionally the new site is identical to the old one. webteam@gatech.edu

Abstract: Vertical cavity surface emitting lasers (VCSELs) along with multimode fiber (MMF) have long dominated the short reach data communication links. As requirements in high speed optical communications continue to increase, these systems are becoming increasingly complex. In order to meet the growing bandwidth demand, optical links are commonly turning to equalization, and multilevel modulation formats. The need for an accurate physics-based rate equation model is critical to the design and analysis of these systems as VCSEL links move past 25Gb/s. To address these links, VCSEL bandwidth is no longer a sufficient metric, since power consumption, noise and device reliability must be taken into account. Therefore there is a growing need for computer-aided design which would help optimize optical links before deployment.
