Optical interconnection networks based on microring resonators [PDF]
, 2012 Optical microring resonators can be integrated on a chip to perform switching operations directly in the optical domain. Thus they become a building block to create switching elements in on-chip optical interconnection networks, which promise to overcome

Rearrangeability of 2×2 W-S-W Elastic Switching Fabrics with Two Connection Rates
Journal of Telecommunications and Information Technology, 2018 The rearreangeable conditions for the 2×2 threestage switching fabric of a W-S-W architecture for elastic optical switches are considered in this paper. Analogies between the switching fabric considered and the three-stage Clos network are shown. On the

Joint Minimization of Spectrum and Power in Impairment-Aware Elastic Optical Networks
IEEE Access, 2021 Flexible-grid elastic optical networks (EONs) are widely considered as the future of next generation optical transport networks. Depleting spectral resources and increasing power consumption are two critical bottlenecks of EONs. In this paper, we propose
