Integrated photonic devices on silicon nitride for next-generation passive optical networks

Passive optical networks (PON) are a key technology to provide broadband Internet services to personal and business users through high-speed fibre cables. This technology has been deployed worldwide for local and access networks. In order to accommodate the drastically increased data volume, the Telecommunication Standardization Sector (ITU-T) has recently defined a 40-Gb/s capacity PON system. […]
