This analysis demonstrates effective demultiplexing with a silicon nitride optical phased array for WDM applications.
This paper discusses the feasibility of a broadband integrated optical phased array (OPA) used for dense wavelength division multiplexing (WDM). The silicon nitride OPA provides the demultiplexing of 1nm~4nm channel spacing for blue-green WDM.
