title: Integrated-optical array generator.
abstract: We demonstrate an optical system that splits one laser beam into an array of N x N equal-intensity beams. It consists of a grating and a diffractive lens, which are integrated on one side of a single planar quartz-glass substrate. The grating and the lens are fabricated with multiple discrete phase levels by using photolithography and thin-film deposition.
