title: Design and rigorous analysis of high-efficiency array generators.
abstract: One-dimensional array generators with seven to fifteen spots are designed by the method of virtual sources in combination with simulated-annealing optimization. Continuous surface-relief grating array generators and their discretized versions are analyzed with rigorous diffraction theory, and the results are compared with those obtained from Fourier-optics theory. The array-generator designs have high diffraction efficiency and good uniformity.
