Recent experiments demonstrate a new technique for confining light in nanoscale waveguides.

Scatterings image(Left to right) Lawrence Berkeley National Laboratory's Xiang Zhang, Ziliang Ye and Volker Sorger have demonstrated the first true nanoscale waveguides for next generation on-chip optical communication systems.

Photonic components of future communications systems will require tight confinement of optical modes over significant propagation distances. The recent experiments of a team at Lawrence Berkeley National Laboratory (U.S.A.) demonstrate a new technique for confining light in nanoscale waveguides (Nature Comm. 2, 331, doi:10:1038/ncomms1315).
