PBH writes: Physicists and engineers at the California Institute of Technology (Caltech) have developed a nanoscale crystal that traps both light and sound.The interaction of light quanta (photons) and sound quanta (phomons) are so strong that they produce mechanical vibrations of tens of gigahertz frequencies. This level of energy will allow a multitude of light wave communication systems at speeds unheard of at present. Multiple applications are possible with present technology.
