Nearly all electronics require devices called oscillators that create precise frequencies - frequencies used to keep time in wristwatches or to transmit reliable signals to radios. For nearly a century, these oscillators have relied upon quartz crystals to provide a frequency reference, much like a tuning fork is used as a reference to tune a piano. A new approach could ultimately replace the quartz crystal frequency reference - technology in use since the 1920s.

Researchers have demonstrated that an array of novel gold, pillar-bowtie nanoantennas can be used like traditional photographic film to record light for distances that are much smaller than the wavelength of light. A standard optical microscope acts as a 'nanocamera' whereas the pillar-bowtie nanoantennas are the analogous film.
