Abstract
This Letter reports the experimental observation of light confinement effects by near-held optical microscopy. Depolarization effects giving rise to light confinement close to nanoscopic objects have been unamb iguously observed in near-held optical images of subwavelength dielect ric pads etched on a flat glass substrate. According to the incident p olarization, this phenomenon leads to reverse contrasts in the near-he ld optical image of the same subwavelength objects.
