We demonstrate experimentally the broadband and adiabatic light transfer in coupled
waveguides based on multiple stimulated Raman adiabatic passage. Our experimental …

We propose a new method for integrating metasurfaces in optical design using semi-
analytical modeling of dielectric nanostructures. The latter computes the output phase of an …

Optical waveguide arrays consisting of a two-dimensional arrangement of weakly coupled
waveguides represent the basis of the new research field of discrete optics. For studying the …

We developed semi-analytical models to efficiently and rapidly obtain the propagation
characteristics of square nanopillar and nanoring meta-atoms. We show that such analytical …

We demonstrate both theoretically and experimentally that discrete diffraction resonance
can be designed, fabricated, and successfully probed in functionalized–guidonic–coupled …

We assess the band structure of arrays of coupled optical waveguides both by ab initio
calculations and by experiments, with an excellent quantitative agreement without any …

In coupled waveguide arrays, well-defined coupling coefficients are still required to
demonstrate advanced effects on a quantitative basis, especially in patterned arrays where …

Since the second half of the 20th century, new photonic materials have gradually emerged
in fundamental and industrial research on an international scale. Metasurfaces, the two …

We present the modified scalar coupled mode analysis for an array of N diffused channel
waveguides. The study simulates the lateral evanescent field coupling in the graded index …

Résumé L'arrivée au début du millénaire des métasurfaces offre une approche novatrice à
la manipulation des ondes électromagnétiques. De l'interaction du front d'onde incident et …
