Light tunneling inhibition and anisotropic diffraction engineering in two-dimensional waveguide arrays
arXiv:0908.3664 · doi:10.1364/OL.34.002906
Abstract
We address two-dimensional waveguide arrays where light tunneling into neighboring waveguides may be effectively suppressed by out-of-phase harmonic modulation of the refractive index in neighboring waveguides at suitable frequencies. Genuine two-dimensional features, such as anisotropic diffraction engineering, diffraction-free propagation along selected directions in the transverse plane and tunneling inhibition for multi-channel vortices, are shown to occur.
