Abstract: Spatial light modulators and associated methods are described. In one embodiment, a spatial light modulator includes a photonic integrated circuit configured for emitting a plurality of light beams as a first waveform by a plurality of pixels. The light beams are individually controllable. The spatial light modulator also includes a meta-optic having a plurality of nanostructures configured for receiving the first waveform and aggregating the plurality of light beams as a second waveform at a surface of the meta-optic. The spatial light modulator also includes an aperture array configured for converting the second waveform into a third waveform, where the third waveform is smaller than the second waveform.
