Numerical Simulations of Trapping Efficiency in One-dimensional Lattice with a Coupling Defect as a Function of Lattice

The numerical calculations related to the light localization in uniform one-dimensional photonic lattice at the local coupling defect position, are performed. It is numerically found the trapping dependence on lattice's parameters. The width of the defect is the main parameter for light localization, but other parameters, such as width of the neighboring waveguides and separations between waveguides, can affect light propagations as well, which is shown here in the paper.
