Fano resonance in quadratic waveguide arrays
A. E. Miroshnichenko, Y. S. Kivshar, R. A. Vicencio +1
We study resonant light scattering in arrays of channel optical waveguides where tunable quadratic nonlinearity is introduced as nonlinear defects by periodic poling of single (or…
All-optical switching and amplification of discrete vector solitons in nonlinear cubic birefringent waveguide arrays
Rodrigo A. Vicencio, Mario I. Molina, Yuri S. Kivshar
We study all-optical switching based on the dynamical properties of discrete vector solitons in waveguide arrays. We employ the concept of the polarization mode instability and dem…
Exponential versus linear amplitude decay in damped oscillators
M. I. Molina
We comment of the widespread belief among some undergraduate students that the amplitude of any harmonic oscillator in the presence of any type of friction, decays exponentially in…
Nonlinear Impurity in a Semi-Infinite Lattice
M. I. Molina
We examine the formation of bound states on a generalized nonlinear impurity located at or near the beginning (surface) of a linear, tight-binding semi-infinite lattice. Using the…
Switching of Discrete Solitons in Engineered Waveguide Arrays
R. A. Vicencio, M. I. Molina, Y. S. Kivshar
We demonstrate a simple method for controlling nonlinear switching of discrete solitons in arrays of weakly coupled optical waveguides, for both cubic and uadratic nonlinearities.…
