Silicon nitride waveguide optical filter components for access network applications
Silicon nitride (SiN) waveguide based micro ring/racetrack resonators to be used as filters in the Chirp Managed Lasers (CMLs) are modelled and demonstrated over the standard silicon (Si) wafer. The development of these racetrack-resonators, with a narrow free spectral range (FSR) of 100GHz is in co...

Silicon nitride (SiN) waveguide based micro ring/racetrack resonators to be used as filters in the Chirp Managed Lasers (CMLs) are modelled and demonstrated over the standard silicon (Si) wafer. The development of these racetrack-resonators, with a narrow free spectral range (FSR) of 100GHz is in correspondence to the international telecommunication union (ITU) recommended channel grid spacing required for the latest next generation passive optical networks (NGPON2) systems. The study of such optical filters, which tend to increase the transmission range of the directly modulated laser (DML) signal, is motivated from the research and development directed towards bringing the CMLs to a reality.
