The invention relates to a process for nanostructuring the surface of a solid material in order to form a regular pattern of nanostructures on said surface, comprising:

Process for nanostructuring the surface of a material by laser

Under consideration here is a method for the production of periodic nanostructuring on one of the surfaces of a substrate (), presenting a periodic network of dislocations, embedded within a crystalline area () located in the neighborhood of an interface () between the crystalline material surfaces of two components () assembled by bonding to form the substrate (). It comprises the following steps:

Method for nanostructuring of the surface of a substrate

The invention concerns a light reflecting element comprising a substrate ( ), a multilayer mirror ( ) and optical coupling means ( ) comprising a diffraction grating ( ); whereby the reflection coefficient of one polarization is damped without damping the reflection coefficient of the orthogonal polarization over a broad wavelength range and with a large tolerance on the optogeometrical parameters of the device.
