Special topic on photonics and AI in information technologies.

Artificial Intelligence (AI) is revolutionizing many aspects of our society, developing a wide variety of real-life applications, from decision-making tasks, such as image classification and autonomous vehicle control, to engineering design, analysis, and manufacturing, such as inverse design. Amin I et al. i [17] wrote an APL Photonics Editor's Pick, demonstrating a novel electro-optic device, which can be used to tune the shape of the neuron nonlinearity based on an ITO-graphene heterojunction integrated absorption modulator in a Si-photonics platform. As a follow-up to a previous APL Photonics special issue on photonics and AI[6] in 2020, the current 2022 APL Photonics special issue discusses the status and future perspectives on photonics and AI in IT, among other topics, highlighting both the role of photonics for AI and the role of AI for photonics.
