Researchers discover directional and long-lived nanolight in a 2D material

An international team led by researchers from Monash University (Melbourne, Australia), University of Oviedo (Asturias, Spain), CIC nanoGUNE (San Sebastián, Spain), and Soochow University (Suzhou, China) discover squeezed light ('nanolight') in the nanoscale that propagates only in specific directions along thin slabs of molybdenum trioxide -- a natural anisotropic 2D material. Besides its unique directional character, this nanolight lives for an exceptionally long time, and thus could find applications in signal processing, sensing or heat management at the nanoscale.
