Abstract
A device for multi-plane conversion of a first light radiation having a conversion block comprising a plurality of optical parts and implementing a plurality of phase masks to apply a spatiofrequential phase shift for producing a second light radiation—a predetermined transformation, known as a transformation with separable variables. The predetermined transformation may link N modes of index {i, j}k, 1<=k<=N, of a first used mode family with separable spatial variables (x,y) describing the first light radiation in a first transverse plane with n modes of the same index {i, j}k 1<=k<=N, of a second used mode family with separable spatial variables (x,y) describing the second light radiation at a second transverse plane. The N modes of the second mode family are not Hermite-Gaussian modes. The N modes of the first mode family are not arranged on the first transverse plane in the form of a triangle.
