Paper Abstract

It was numerically and experimentally shown that square-profile microsteps with width of 0.4 μm, 0.5 μm, 0.6 μm, 0.8 μm and height of 500 nm illuminated by linearly polarized laser light with wavelength λ = 633 nm formed near its’ surface photonic nanojets with intensity that is 6 times higher than the intensity of incident light. Experimentally measured diameters of photonic nanojets were equal to 0.44λ, 0.43λ, 0.39λ and 0.47λ (less than the diffraction limit 0.51λ).
