Rigorous diffraction theory is applied for the first time to the analysis of periodic, binary computer-generated holographic optical fan-out elements, often called Dammann gratings. The effects of the length of the grating period on the reconstruction noise and the diffraction efficiency are analyzed and discussed. Novel schemes are proposed for producing compact and highly efficient space-invariant optical interconnects that operate in the resonance domain. © 1991.
