DARK PHYSICS BEATS LIGHT LIMIT
Current laser-based techniques to make computer chips cannot
fashion components much smaller than the light's wavelength, but
researchers are devising tricks to beat this so-called diffraction limit.
A new idea, detailed in an upcoming Physical Review Letters, is to use
a dark state--which requires multiple laser beams--to write patterns
in the absorbing material. Calculations show that the technique could
create structures far smaller than the beams' wavelengths without using
the dangerously high intensities needed with other proposed techniques.
