In this episode of Photonics Hot List:

Holograms are continuing to advance into real-world applications, with the design of an optical system that combines them with AI to encode information and data. Researchers in Greece, who developed the new system, say this paves the way for stronger digital security.

In business news, Hamamatsu Photonics has launched an awards program they say is meant to boost photonics technology and push market-ready solutions. Elsewhere, LightSolver and Ansys are joining forces, and LightPath Technologies announces its acquisition of G5 Infrared.

Researchers in Europe are tapping into the quantum mechanical principle of strong light-matter coupling to design thin-film polariton filters. The team says their findings could potentially revolutionize displays, sensors, and optical imaging technologies.
