Résumé

We demonstrate an optical arbitrary waveform measurement (OAWM) technique that exploits optical frequency combs as multi-wavelength local oscillators (LO) and that does not require any optical slicing filters. In a proof-of-concept experiment, we achieve record-high bandwidths exceeding 600 GHz. (C) 2022 The Author(s)

Démonstration (logique et mathématiques)

vignette| : un des plus vieux fragments des Éléments d'Euclide qui montre une démonstration mathématique. En mathématiques et en logique, une démonstration est un ensemble structuré d'étapes correctes de raisonnement. Dans une démonstration, chaque étape est soit un axiome (un fait acquis), soit l'application d'une règle qui permet d'affirmer qu'une proposition, la conclusion, est une conséquence logique d'une ou plusieurs autres propositions, les prémisses de la règle.

Computer-assisted proof

A computer-assisted proof is a mathematical proof that has been at least partially generated by computer. Most computer-aided proofs to date have been implementations of large proofs-by-exhaustion of a mathematical theorem. The idea is to use a computer program to perform lengthy computations, and to provide a proof that the result of these computations implies the given theorem. In 1976, the four color theorem was the first major theorem to be verified using a computer program.

Proofs and Refutations

Proofs and Refutations: The Logic of Mathematical Discovery is a 1976 book by philosopher Imre Lakatos expounding his view of the progress of mathematics. The book is written as a series of Socratic dialogues involving a group of students who debate the proof of the Euler characteristic defined for the polyhedron. A central theme is that definitions are not carved in stone, but often have to be patched up in the light of later insights, in particular failed proofs. This gives mathematics a somewhat experimental flavour.

Microresonator-based solitons for massively parallel coherent optical communications

Solitons are waveforms that preserve their shape while propagating, as a result of a balance of dispersion and nonlinearity(1,2). Soliton-based data transmission schemes were investigated in the 1980s and showed promise as a way of overcoming the limitatio ...
