Man makes microscopic Olympic Torch

A student has created his very own Olympic Torch - 100,000 times smaller than the original.

Peter Kremer, from Heriot-Watt University in Edinburgh, accidentally reproduced the torch on the nanoscale while carrying out research into light particles. He was trying to make an antenna to help funnel a wave of light into and out of a quantum dot - a portion of matter whose smallest parts are confined in all three spatial dimensions.

The 28-year-old PhD student came up with the nano-torch a month ago while experimenting with cones to channel the light down.
