Short-visible-wavelength GHz Spot Arrays for Atom Control

ORAL

Abstract

Integrated photonic devices offer a path to perform site-addressable quantum gates on thousands of atomic systems, pushing beyond the limits of bulk optical modulators. Integrated photonic platforms with transparency in the blue and ultraviolet—wavelengths required for many quantum gate protocols—are less developed than platforms for the visible or telecom. Here, we report on conversion of light from an array of thin-film-lithium-niobate integrated photonic modulators to 420nm via sum-frequency generation with a strong pump beam. We report GHz switching speeds, dynamic redistribution of output power, and outline a path to address a thousand atomic targets.
