The ring-based optical Resonant Router

The Resonant Router (ReR) is an integrated optics crossbar matrix based on ring resonators. Depending on the characteristics of the rings the ReR can operate as cross-connect (X-ReR) or as wavelength router (λ-ReR). The analysis of the device, the spectral characteristics and the impact on a high bit rate signal are presented and discussed both on theoretical and experimental basis. The ReR can add flexibility and extend the capabilities of a node of a transparent optical network.
