The small world as seen through a scanning electron microscope - photonics.intec.ugent.be
Take the length of the equator on the map above, double that distance and you have the width of a human hair. For this is the world’s smallest world map, with the 40,000 kilometre-long equator reduced to a mere 40 micrometres.The smallest features on the map, corresponding to 100 kilometres, are about 100 nanometres wide.
The world map hidden in the bottom right corner of a photonic chip
The map was created by the Photonics Research Group at Ghent University in Belgium, and embedded in an optical silicon chip[above]. Miniaturisation on this scale (one trillionth [*], to be exact) will enable optical technology with a million times more components than in present-day, glass-based photonics, and opens the door to nanophotonic applications in consumer electronics[but, of course!], medical imaging, and telecommunications.
*: The factor of 1 trillion ( is expressed by the prefix tera- (as in terabyte or teraflop)
