Abstract
Light-based methods are fundamental in biomedical and life sciences as non-invasive diagnostic and treatment tools. However, the scattering nature of biological tissue limits the maximum depth at which they can operate – typically, below one millimeter. Here, we show how ultrasound waves inside a resonant cavity can locally modulate the optical properties of a turbid medium. In agreement with Monte Carlo simulations, our experimental results demonstrate, at an optical density of 15, an enhancement in light confinement up to a factor of 7 compared to conventional methods.
