Abstract

We address free-space optical interconnections based on cascaded multifacet holographic elements, including an intermediate regeneration of the optical signals. Particular attention is paid to digital hologram encoding in the case of highly interconnected planes. Degrees of freedom selected in the reconstruction plane are used for satisfying both holographic-encoding and signal constraints. An iterative Fourier-transform algorithm is chosen because of its ability to incorporate constraint considerations.
