Infrared antenna for nano-size mapping of crystal vibrations
...age. By exploiting phonon resonance, photonics and microscopy are seen to expand from the traditional visible spectrum (0.4 - 0.7 m), or the near infrared of telecommunication (1.5 m), to also include the mid-infrared (3 - 30 m) where crystal lattice vibrations occur.
