Figures & Tables(9)
Fig. 1. (Color online) Schematics of (a) 2D Mesh network of a 16-core CMP and (b) four-port optical router. The blue squares indicate processor cores, yellow dots indicate optical routers, and lines with arrows indicate optical waveguides.
Fig. 2. (Color online) Schematics of (a) the optical router and (b) the microring optical switch.
Fig. 3. (Color online) Micrograph of the fabricated optical router.
Fig. 4. (Color online) Static spectral responses of the microring switch element on its “cross” and “bar” states.
Fig. 5. (Color online) Optical SNRs of the four-port optical router in the selected three routing states, which cover its all 12 optical links. Each row represents a single routing state with identical output port in each column. Notation P represents the overall power consumption of each routing state.
Fig. 6. (Color online) For all 12 optical links, eyes diagrams at corresponding output ports, 40 Gbps 231–1 PRBS optical signal at wavelength 1547.37 nm is used.
Fig. 7. (Color online) WDM data transmission through the optical link Ei → So.
