Discrete $X$-Wave Formation in Nonlinear Waveguide Arrays Academic Article uri icon

abstract

  • Abstract We present experimental evidence for the spontaneous formation of discrete X waves in AlGaAs waveguide arrays. This new family of optical waves has been excited, for the first time, by using the interplay between discrete diffraction and normal temporal dispersion, in the presence of Kerr nonlinearity. Our experimental results are in good agreement with theoretical predictions.
