(Nanowerk Spotlight) Quantum light sources are a fundamental building block for many quantum technologies, enabling secure communication, powerful computing, and precise sensing and imaging.

This paper covers a discussion of the Abbe Sine Condition and its implication for Flat Optics, including the effects of stop shift and substrate curvature. Following that, we apply Sweatt’s high index ...
