通过纳米同轴"光"缆对光进行挤压

美国物理学家创造了世界上第一个用于光传输的纳米尺度同轴"光"缆。与用于传输电视和收音机信号的同轴电缆的类似,同轴"光"缆可以传送波长将近4倍于其直径(200nm)的光信号。研究人员还声称,在小于波长的距离上对光进行控制的能力可能会有利于制作更好的光学显微镜,更小的计算机芯片以及更有效的太阳能电池等。

Light squeezes through nano coax (Jan 10)

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)
