Accelerating Lightpath setup via broadcasting in binary-tree waveguide in Optical NoCs

In this paper, we propose a binary-tree waveguide connected Optical-Network-on-Chip (ONoC) to accelerate the establishment of the lightpath. By broadcasting the control data in the proposed power-efficient binary-tree waveguide, the maximal hops for establishing lightpath is reduced to two. With extensive simulations and analysis, we demonstrate that the proposed ONoC significantly reduces the setup time, and then the packet latency.
