SUMMARY:FlexLION: Scalable and Reconfigurable All-to-All Photonic Intercon
 nects
DESCRIPTION:Roberto Proietti, Xian Xiao, Sebastian Werner, and Pouya Fotou
 hi (University of California, Davis); Jeff Messig (Enablence Technologies 
 Inc); and S.J. Ben Yoo (University of California, Davis)\n\nWe propose Fle
 xLION (Flexible Low-Latency Interconnect Optical Network) to pursue energy
 -efficient, scalable, and reconfigurable all-to-all silicon photonic (SiPh
 ) interconnects. FlexLION offers contention-less and arbitration-free all-
 to-all communication among selected nodes (processors or electronic switch
 es) while providing bandwidth-adaptive interconnection between the other n
 odes. The proposed technology consists of a scalable all-to-all Thin-CLOS 
 architecture [1] based on arrayed waveguide grating routers (AWGRs) combin
 ed with micro-ring-based flexible wavelength selective filters and optical
  MEMS (Microelectromechanical systems) [2]. Benchmarking simulation studie
 s indicate ≥ 3× energy efficiency improvements compared to state-of-the-ar
 t switching solutions for typical workloads. At the SC14 Emerging Technolo
 gies track, we presented the first all-to-all optically-interconnected 8-n
 ode testbed demo with 32-port AWGRs and FPGA-based nodes, and at SC17, we 
 reported  technology advancements toward close 2.5D integration between el
 ectronic ICs and silicon photonic transceivers interconnected by AWGRs. Fo
 r the SC18 Emerging Technology showcase, we will present the following inn
 ovations: (1) design, fabrication and testing of a 64-port All-to-All Thin
 -CLOS AWGR prototype; (2) architecture and simulation studies for the prop
 osed FlexLION; (3) current research activities toward SiPh integration of 
 FlexLION.\n\nRegistration Category: Tech Program Reg Pass, Exhibits Reg Pa
