Could light be used to transmit information between satellites and Earth? Atmospheric water vapor scatters and absorbs light energy, but overcome that obstacle, and light will carry far more information and move it faster than the radio waves we currently rely on. A new research project, supported by the National Geospatial-Intelligence Agency, proposes to use the properties of light itself to punch a pathway for data through the clouds.
“My work is understanding the constituents of light and manipulating them to interact with matter. In recent years, we’ve seen more advances in using light for biomedical imaging and quantum computing, but the fundamental properties of manipulating light are the same, and light can be
