DeEPeR

This paper presents an efficient device-level design method to enhance the performance and reliability (DeEPeR) in optical interconnection networks (OINs) under fabrication process variations (PV). Considering different range of variations, DeEPeR explores the design space of fundamental optical components in OINs (e.g., microresonators (MRs)) to improve the overall system performance and reliability. Our study also includes the design and fabrication of several MRs to experimentally validate our proposed method. Moreover, as a system-level case study, we apply DeEPeR to a general passive OIN under PV. Results indicate that DeEPeR considerably improves the optical signal-to-noise ratio (OSNR) in optical interconnection networks.
