Features of the Application of Ring Resonators for Deinterleaving in WDM Systems

The principles of using ring optical resonators for preliminary demultiplexing of the group signal of systems with wavelength division and multiplexing of channels are proposed. The construction of the group signal deinterleaving system is given. The variant of building a multi-cascade system for deinterleaving is shown. The possibility of additional purification of the group signal from parasitic combinational components and increase of the signal/noise ratio has been demonstrated.
