Scientists Learn To Steer Light at the Nanoscale, Setting New Records

Researchers have introduced an innovative two-step excitation approach that makes it possible to efficiently generate and clearly separate different modes of hyperbolic polaritons. An international collaboration of scientists has introduced a new approach for generating and manipulating extremely confined light–matter waves called higher-order hyperbolic phonon polaritons (HPhPs). Using this method, the researchers achieved record levels [...]
