The design and the implementation of a modular spot-array generator for a modulator-based free-space optical interconnect is presented. Two cascaded diffractive optical elements produce 4 ϫ 8 clusters on a 1600 m ϫ 800 m pitch, where each cluster is a 4 ϫ 4 array of ͑1͞e 2 ͒ 13.1-m-radius spots on a 90-m pitch. The spot-array generator is kinematically aligned to the interconnect system such that no realignment is necessary between removal and reinsertion. Characterization results are presented.
