Paper Abstract

Several methods for transforming the spatial properties of optical beams in nonlinear photonic crystals are reviewed. Successive up-conversion and down conversion a periodic 1D nonlinear photonic crystal enables to convert the fundamental Gaussian beam to a higher order Hermite Gaussian beam at the same wavelength. Nonlinear deflection over a wide spectral and temperature range is enabled by a specific two-dimensional modulation of the nonlinear coefficient. Finally, nonlinear generation of vortex beams can be achieved by specific three-dimensional modulation of the nonlinear coefficient.
