First device based on 'optical thermodynamics' can route light without switches. Your thoughts?

University of Southern California / September 2025

From the abstract:

By deploying entropic principles, here we demonstrate a counter-intuitive optical process in which light, launched into any input port of a judiciously designed nonlinear array, universally channels into a tightly localized ground state, a response that is completely unattainable in linear conservative arrangements.
