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: The objective of this research is to investigate the impact of radiation caused by high-energy particles in integrated silicon photonic components and systems. Deep-space optical communications have been proposed to increase data bandwidths and reduce the size, weight, power, and cost of legacy electrical systems. Integrated silicon photonics technology has become a contender to realize these space systems due to their rapid advancement in terrestrial systems over the past decade. However, little is known about this technology's response to and system-level impact of various radiation effects. To better understand the limitations of silicon photonics for space applications, several experiments with single-event radiation and total-ionizing dose were conducted on various integrated components. These experiments show that, while this research is still in its infancy, silicon photonics technology is a viable solution to realize optical communications systems for space applications due to its radiation resiliency.
