Paper Abstract

This work presents the analysis of ring resonator based tuneable optical filters and their proposed application in wavelength division multiplexing transmission systems. Using coupled mode theory and its transfer matrix formalism it has been shown that single-ring resonator add-drop filters with coupling coefficients k can provide similar or better performance than double ring resonator add-drop filters with coupling coefficients k/2, while benefiting from simple and more robust designs, simplified tuning control, and easier manufacturing. Further analysis of the their dynamic range showed that thermally tuneable single-ring add-drop filters can easily cover four optical channels at 0.8nm spacing. Their proposed application is a sparse reconfigurable optical add-drop multiplexer with 0.25 add-drop factor and 32 channels at 0.8nm channel spacing that can be utilized in linear, ring, and mesh all-optical WDM networks/transmission systems.
