In an effort to enhance photonic and electronic circuitry utilized in semiconductor chips and fiber optic networks, researchers at the McKelvey School of Engineering at Washington University in St. Louis modified the principles of physics that dictate the propagation of light over time and distance. They have unveiled a new approach to control light transmission, which opens avenues for sophisticated optical devices.

Their approach creates a “mirror-flip of the system,” explained Lan Yang, the Edwin H. & Florence G. Skinner Professor of electrical and systems engineering and lead author of the study, now featured in Science Advances.

Through this research, they have established a means for light to flow through a system in solely one direction. This “asymmetric transmission” represents one of the primary results of this study as it can enhance the efficiency of telecommunication systems.
