Light squeezes through nano coax (Jan 10)
http://physicsweb.org/article/news/11/1/6
Physicists in the US have created the first nanoscale coaxial cables for
the transmission of light. Operating much like the coaxial cables used
to distribute television and radio signals, the cables can transmit
light with wavelengths nearly four times their 200 nm diameter. The
researchers claim that the ability to control light over sub-wavelength
distances could lead to better optical microscopes, smaller computer
chips and more efficient solar panels (Appl Phys Lett 90 021104)
