Nanoscale self-organisation and metastable non-thermal metallicity in Mott insulators
Andrea Ronchi, Paolo Franceschini, Andrea De Poli +10
Mott transitions in real materials are first order and almost always associated with lattice distortions, both features promoting the emergence of nanotextured phases. This nanosca…
Wavelength flattened directional couplers: a geometrical approach
Matteo Cherchi
A new approach to design wavelength insensitive optical power splitter is presented. First coupled-mode theory is cast in operatorial form. This allows to solve the equivalent of c…
Exact analytic expressions for electromagnetic propagation and optical nonlinear generation in finite one-dimensional periodic multilayers
Matteo Cherchi
Translation Matrix Formalism has been used to find an exact analytic solution for linear light propagation in a finite one-dimensional (1D) periodic stratified structure. This moda…
Wavelength flattened directional couplers for mirrorsymmetric interferometers
Maurizio Tormen, Matteo Cherchi
In the context of guided optics, we derive, analytically and geometrically, a rigorous general criterion to design wavelength insensitive interferometers with mirror symmetry, whic…
Bloch Analysis of Finite Periodic Microring Chains
Matteo Cherchi
We apply Bloch analysis to the study of finite periodic cascading of microring resonators. Diagonalization of the standard transfer matrix approach not only allows to find an exact…
Spatial and temporal characterization of a Bessel beam produced using a conical mirror
K. B. Kuntz, B. Braverman, S. H. Youn +3
We experimentally analyze a Bessel beam produced with a conical mirror, paying particular attention to its superluminal and diffraction-free properties. We spatially characterized…
