Paper Abstract

We identified nanostructured devices sustaining subwavelength diffraction-free beams with grazing propagation. The components of the optical assembly are a metal-dielectric multilayer stack deposited on a solid transparent substrate. Launched from the substrate, the nondiffracting beam is resonantly transmitted though the stratiform medium leading to light confinement and wave amplification around the beam axis near the top end. Potential applications include optical trapping, biosensing, and nonlinear optics.
