Extended Data Fig. 1: Optical module for generation of trapping light.

The light enters by means of a single-mode fibre that is collimated and then converted into a uniform intensity line with a diffractive optical element. The line is then divided into N lines by driving an AOD with N RF tones. This procedure is performed in two paths to create arrays of horizontal and vertical lines. The arrays are then combined on a polarizing beam splitter to create the grid of trap light, which is imaged onto the atoms.
