title: Optical coherence gratings and lattices.
abstract: We introduce a class of partially coherent temporal/spatial sources, optical coherence gratings/lattices that have a Gaussian intensity profile and statistically stationary/homogeneous, periodic temporal/spatial coherence properties. We show that temporal coherence gratings generate partially coherent pulses with periodic spectra, whereas spatial coherence lattices yield far-zone output in the form of periodic lattices of highly directional beams.
