    • Abstract:
      The article reports that physicists at Boston College (BC) in Chestnut Hill, Massachusetts have reported that nanoscale coaxial waveguide can guide visible light. The waveguide distributes light in transmission electron microscopy (TEM) mode of a coaxial waveguide, however it measures only 300 nanometer (nm) in diameter.
