Harvard researchers have developed techniques to control “points of darkness” in light using metasurfaces. The team created precise dark spots that can capture atoms or act as measurement points for imaging, and developed resilient “polarization singularities,” stable dark spots in polarized optical fields.

Harvard Scientists Control “Points of Darkness” for Remote Sensing and Covert Detection Applications
Two studies report new methods for using metasurfaces to create and control dark areas called “optical singularities.” Optical devices and materials allow scientists and engineers to harness light for research and real-world applications, like sensing and microscopy. Federico Capasso’s group at t
