SUMMARY:FlexLION: Scalable and Reconfigurable All-to-All Photonic Intercon

DESCRIPTION:Emerging Technologies\nTech Program Reg Pass, Exhibits Reg Pas
 s, Exhibits - Exhibit Hall Only Reg Pass\n\nFlexLION: Scalable and Reconfi
 gurable All-to-All Photonic Interconnects\n\nProietti, Xiao, Werner, Fotou
 hi, Messig...\n\nWe propose FlexLION (Flexible Low-Latency Interconnect Op
 tical Network) to pursue energy-efficient, scalable, and reconfigurable al
 l-to-all silicon photonic (SiPh) interconnects. FlexLION offers contention
 -less and arbitration-free all-to-all communication among selected nodes (
 processors or electronic switches) while providing bandwidth-adaptive inte
 rconnection between the other nodes. The proposed technology consists of a
  scalable all-to-all Thin-CLOS architecture [1] based on arrayed waveguide
  grating routers (AWGRs) combined with micro-ring-based flexible wavelengt
 h selective filters and optical MEMS (Microelectromechanical systems) [2].
  Benchmarking simulation studies indicate ≥ 3× energy efficiency imp
 rovements compared to state-of-the-art switching solutions for typical wor
 kloads. At the SC14 Emerging Technologies track, we presented the first al
 l-to-all optically-interconnected 8-node testbed demo with 32-port AWGRs a
 nd FPGA-based nodes, and at SC17, we reported  technology advancements tow
 ard close 2.5D integration between electronic ICs and silicon photonic tra
 nsceivers interconnected by AWGRs. For the SC18 Emerging Technology showca
 se, we will present the following innovations: (1) design, fabrication and
  testing of a 64-port All-to-All Thin-CLOS AWGR prototype; (2) architectur
 e and simulation studies for the proposed FlexLION; (3) current research a
 ctivities toward SiPh integration of FlexLION.
