Optical network-on-chip (ONoC) is a new type of network on chip (NoC) for multiprocessor system-on-chip. While traditional NoC relies on electrical signals to transfer information, hence called electrical network-on-chip (ENoC), its performance and energy efficiency are bound by the significantly unbalanced scaling of on-chip global metal wires comparing to transistors.
