Most of microwave devices are not optically transparent in the visible range. Optically transparent microwave devices, such as absorbers, filters and antennas, would be desirable since they could be fully exploited for shielding systems, military applications or integrated in window glasses and along with photovoltaics. These devices could also play a key role in micro- and nano-satellite applications...
The integration of graphene in high frequency devices envisages the possibility to realize new components for microwave, terahertz up to optical frequency ranges. In this paper, we will discuss the latest achievements and new perspectives in graphene-based devices for applications such as communication engineering, photonic technology and sensing. We will also review our recent results on modeling...
We present a platform for the optical interconnection of traffic nodes where the sense of transmission is exploited as an additional degree of flexibility. Implementation of the optical arrangement is shown. The requirements about the negotiation of the available resources, such as fibers and wavelengths, are discussed. We evaluate the implications of flexible-sense transmission in terms of cost,...
We propose a scheme for efficient power control in 100G optical transponders through reduction of the length of electronic chromatic dispersion compensation filters, according to the network traffic fluctuations. Transmission rate reduction is achieved by symbol retransmission, while maintaining system parameters unchanged, to avoid increased complexity. Power savings offered by the scheme are estimated.
