| titleOfInvention | DEVICE FOR CONTROLLING THE PHASE OF AN OPTICAL WAVEFRONT |
| abstract | According to one aspect, the invention relates to a device (20, 50) for controlling the phase of an incident optical wavefront of wavelength within a given spectral band of use, comprising a substrate (21) at least partially transparent in said spectral band and a set of blades (22i, 23i, 24i) disposed substantially perpendicular to the surface of the substrate, characterized in that: - said set of blades comprises an alternation of juxtaposed blades, respectively metallic material (22i), in a first dielectric material (23i) and in at least a second dielectric material (24i) different from the first dielectric material, so as to form juxtaposed metal-multi-dielectric-metal (MmultiDM) structures (Si), of widths (w w) at wavelength, each structure forming a cavity having one or more modes of propagation, the respective thicknesses of the blades made of first dielectric material, t second (s) material (s) dielectric (s) are adjusted in each of said structures MmultiDM to induce a local phase shift (ΔΦi) wavefront phase proportional to the effective index of the mode (s) adapted (s) to propagate in said cavity. |
