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

An international research team reports that light confined in the nanoscale propagates only in specific directions along thin slabs of molybdenum trioxide, a natural anisotropic 2-D material. Besides its unique directional character, this nanolight propagates for an exceptionally long time, and thus has possible applications in signal processing, sensing and heat management at the nanoscale.
