    • Fano resonances in waveguide arrays with saturable nonlinearity 
      Naether, Uta; Rivas, Daniel E.; Larenas, Manuel A.; Molina Gálvez, Mario; Vicencio Poblete, Rodrigo (Optical Society of America (OSA), 2009)
      We study a waveguide array with an embedded nonlinear saturable impurity. We solve the impurity problem in closed form and find the nonlinear localized modes. Next, we consider the scattering of a small-amplitude plane ...
