In recent years, scientists have been able to transmit light through opaque surfaces, such as white paint or human tissue, which had once been considered impossible. However, a technique for controlled light delivery to a region inside an opaque medium has remained elusive, as well as an understanding of the fundamental limitations.
Researchers in the lab of Hui Cao, the John C. Malone Professor of Applied Physics, Professor of Physics and of Electrical Engineering, find the ultimate limit for energy deposition anywhere inside a diffusive system - that is, material that strongly scatters light and look opaque, such as human tissue. The results are published today in Nature Physics.
