Abstract

We describe a phase plate based on the fractional-Talbot effect that converts a single expanded laser beam into a regular array of uniformly illuminated apertures with virtually 100% efficiency. The size, spacing, and fill factor of the illuminated aperture grid can be freely chosen to interface with a variety of electro-optic devices. A binary-optics phase plate is demonstrated that converts uniform illumination into an array of square illumination cells with a fill factor of 1/16.
