The new "p-n junction": Plasmonics enables photonic access to the nanoworld [PDF]

, 2005
Since the development of the light microscope in the 16th century, optical device size and performance have been limited by diffraction. Optoelectronic devices of today are much bigger than the smallest electronic devices for this reason.
