Bowtie Photonic Crystal Allows Extreme Light Concentration with Low Loss
NASHVILLE, Tenn., Aug. 27, 2018 — A new nanostructure that is part bowtie and part funnel has been shown to focus and conduct light powerfully and nearly indefinitely, as measured by a scanning near-field optical microscope. The bow-tie photonic structure, developed by a team at Vanderbilt University, allows light to be squeezed into very small volumes, which yield very high levels of energy. The Vanderbilt team collaborated with researchers at the IBM T.J. Watson Research Center and the University of Technology in Troyes,
