"Breakthrough: Two-Dimensional Waveguides Uncovered by Research Team"
The U.S. Naval Research Laboratory and Kansas State University have discovered slab waveguides based on the two-dimensional material hexagonal boron nitride, which can be used to enhance spectroscopy of encapsulated 2D materials. These waveguides, reported in the journal Advanced Materials, have the potential to impact the development of atomically thin electronic and optical devices, offering a way to study elusive dark excitons optically and providing a step towards interfacing 2D materials with existing platforms without damaging them.
