Squeezed light in the nanoscale (“nanolight”) was found to propagate only in specific directions along thin slabs of a natural anisotropic 2D material, molybdenum trioxide (α-MoO3). The discovery was made by an international team of researchers from Monash University, University of Oviedo, CIC nanoGUNE, and Soochow University.
