The contention detection subsystem provides all the necessary control signals required to drive an optically-controlled buffer which employs 1x2 optical switching elements and an optical fiber delay line (FDL). The state of the buffer is dynamically controlled on a per packet basis with all the decisions and processing performed in the optical domain. Physical layer simulations show successful buffering and forwarding of 40 Gb/s optical packets with 2 dB power penalty.

Optical packets are self-routed on a hop-by-hop basis through the network by using stacked optical tags, each representing a specific optical node. Each tag contains control signals for configuring the switching matrix and forwarding each packet to the appropriate outgoing link and onto the next hop. Physical layer simulations are performed, modeling each optical sub-system of the node showing acceptable signal quality and Bit Error Rates. Resource reservation-based signaling algorithms are theoretically modeled for the control plane capable of providing high performance in terms of blocking probability and holding time.

In this article, we present our recent work spanning from Si-based integrated optical RAM cell architectures up to complete optical cache memory architectures for Chip Multiprocessor configurations. Moreover, we discuss on e/o router subsystems with up to Tb/s routing capacity for cache interconnection purposes within CMP configurations, currently pursued within the FP7 PhoxTrot project.
