Recent Advances in Light Matter Interactions in Temporal Media 14 7

Abstract

In this review, the progress in research and development in the field of electromagnetic wave propagation through temporal/time-varying media is presented. Temporal/time-varying media refers to materials or environments whose properties change over time. Therefore, unlike spatial waveguides that manipulate light based on the spatial configuration of the structure, temporal waveguides focus on the evolution of light pulses over time. Understanding temporal media is essential for developing advanced communication protocols, efficient waveguides, and accurate simulations of physical systems, ultimately improving the design and performance of various applications in science and technology. Controlled light–matter interactions in the time domain offer numerous advanced applications for secure optical communication, information processing, and ultrafast optics in the realm of quantum technology. Recent advances in light–matter interactions in temporal media have opened exciting avenues for manipulating light at unprecedented levels, leading to novel applications in fields such as quantum computing, telecommunications, and materials science.
