Strictly speaking it was a spaser --, or surface plasmon laser. Now it's the turn of researchers at the University of California at Berkeley. This week in an article in Nature the Berkeley researchers claim to have created the smallest semiconductor laser ever. Their new device can generate light in a space just 5 nm in size.
