Coherent holographic grating interconnect systems exhibit deleterious interference effects when multiple optical beams are fanned into a single beam with the use of multiplexed gratings. Elimination of such effects is possible with the use of arrays of incoherent sources for readout, temporal sequencing, random phase modulation of the readout beams, or allocated volume configurations. The merits and drawbacks of each alternative are analyzed.
