Abstract

Spatial effects of interference and interaction of light modes in the subwavelength part of the near-field optical microscopy probe have been theoretically studied. It was found that the mode interference can lead to higher spatial compression of light (wavelength is equal to 500nm in free space) within the transverse size of 25nm inside the probe output aperture of 100nm in diameter. The results predict a principal possibility of higher spatial resolution in the near-field optical microscopy technique.
