QuT: A Low-Power Optical Network-on-Chip
To enable the adoption of optical Network-on-Chips (NoCs) and allow them to scale to large systems, they must be designed to consume less power and energy. Therefore, optical NoCs must use a small number of wavelengths, avoid excessive insertion loss and reduce the number of microring resonators. The authors propose the Quartern Topology (QuT), a novel low-power all-optical NoC. They also propose a deterministic wavelength routing algorithm based on Wavelength Division Multiplexing that allows the user to reduce the number of wavelengths and microring resonators in optical routers.
