There is, I think, something ethereal about i —the square root of minus one. I remember first hearing about it at school. It seemed an odd beast at that time—an intruder hovering on the edge of reality.

Usually familiarity dulls this sense of the bizarre, but in the case of i it was the reverse: over the years the sense of its surreal nature intensified. It seemed that it was impossible to write mathematics that described the real world in …

I and i

We present the science and technology roadmap for graphene, related two-dimensional crystals, and hybrid systems, targeting an evolution in technology, that might lead to impacts and benefits reaching into most areas of society. This roadmap was developed within the framework of the European Graphene Flagship and outlines the main targets and research areas as best understood at the start of this ambitious project. We provide an overview of the key aspects of graphene and related materials (GRMs), ranging from fundamental research challenges to a variety of applications in a large number of sectors, highlighting the steps necessary to take GRMs from a state of raw potential to a point where they might revolutionize multiple industries. We also define an extensive list of acronyms in an effort to standardize the nomenclature in this emerging field.

Information Theory and Reliable Communication

We propose the use of input-output cross correlations to quantify the performance of four-wave mixing time lenses with dispersion-induced degradation. The impact of disper­sion variations is investigated.

Characterization of the Impact of β 2 and β 3 in Four-Wave Mixing Optical Time Lenses using Input-Output Cross-Correlations

The present invention relates to a method for providing a radio frequency signal for transmission, a system for providing a radio frequency signal for transmission and a method for wireless data transmission between a transmitter and a receiver.

Wireless data signal transmission system

This paper will discuss time lenses and their broad range of applications. A number of recent demonstrations of complex high-speed optical signal processing using time lenses will be outlined with focus on the operating principle.

High-Speed Optical Signal Processing Using Time Lenses

We present frequency comb generation in crack- and annealing-free Si 3 N 4 microresonator chips fabricated using novel Si-photonics compatible processing.

We present an experimental characterization of longitudinal zero-dispersion wavelength variations in a novel, strained, highly nonlinear fiber, by simple four-wave mixing spectrum analysis, and provide new insights to the analysis supported by detailed numerical simulations.
