Abstract
A diffractive optical apparatus has a planarly expansive, diffracting structure with a plurality of structural sub-regions, each of this sub-regions directing a portion of a light falling thereon to onto other spatial points allocated to the structural sub-regions independently of the remaining structural sub-regions. Diffracting structure provides beam splitting with a high fan out and high efficiency for use, for example, in computers at a board level or chip level.
