Abstract

The fundamental choice to be taken when sharing an optical ring between multiple communication actors is whether to avoid contention from the ground up by means of non-interfering concurrent transmissions on different wavelengths, or by resolving it at runtime through arbitration mechanisms.This paper aims at assessing power efficiency of Wavelength-Selective vs. Wavelength-Arbitrated routing methodologies on top of an optical ringfor photonically-integrated high-end embedded systems.
