Abstract

This paper discusses an optical continuum as a key technique to help telecom operators reduce the total cost of ownership (TCO) of their optical networks. Enabling photonic technologies are reviewed, with a focus on recent advances in reconfigurable optical add drop multiplexers (ROADMs) based on silicon photonics.
