Abstract Solutions for scalable, high-performance optical control are important for the development of scaled atom-based quantum technologies. Modulation of many individual optical beams is central to applying arbitrary gate and control sequences on arrays of atoms or atom-like systems. At telecom wavelengths, miniaturization of optical components via photonic integration has pushed the scale and performance of classical and quantum optics far beyond the limitations of bulk devices. However, material platforms for high-speed telecom integrated photonics lack transparency at the short wavelengths required by leading atomic systems. Here, we propose and implement a scalable and reconfigurable photonic control architecture using integrated, visible-light modulators based on thin-film lithium niobate. We combine this system with techniques in free-space optics and holography to demonstrate multi-channel, gigahertz-rate visible beamshaping. When applied to silicon-vacancy artificial atoms, our system enables the spatial and spectral addressing of a dynamically-selectable set of these stochastically-positioned point emitters. 

We present a novel Phase Retrieval algorithm that is able to uniquely recover a complex object from its noise-corrupted Fourier magnitudes in an arbitrary number of dimensions while running in O(N Log N) time. 

We present a device of thin film lithium niobite integrated on a CMOS backplane, enhanced by a high quality factor guided mode resonance. The device offers GHz speed and megapixel degrees-of-freedom spatial light modulation.
