Optical routing for 3D system-on-package

ABSTRACT

Optical interconnects enable faster signal propagation with virtually no crosstalk. In addition, wavelength division multiplexing allows a single waveguide to be shared among multiple interconnects. This paper proposes efficient algorithms for the construction of timing and congestion-driven waveguides considering the optical resource constraints. We develop the first optical router for System-on-Packages (SOPs), which reduce electrical wirelength by 11% and improve performance by 23%, when a single optical layer is introduced for every placement layer.
