Natural and manmade physical structures all lose energy, and scientists work hard to eliminate that loss or compensate for it. Optical and photonic devices lose energy through light scattering, radiation or material absorption. In some situations, however, intentionally yet carefully designing loss in open optical devices and systems can lead to unconventional physical phenomena, which inspire novel methods for optical control and engineering.
Lan Yang, the Edwin H. & Florence G. Skinner Professor in electrical and systems engineering at the McKelvey School of Engineering at Washington University in St. Louis, along with a team that includes A. Douglas Stone and his lab at Yale University, uncovered new approaches to manipulating light absorption.
