Symmetric and antisymmetric nonlinear modes supported by dual local gain in lossy lattices
We introduce a discrete lossy system, into which a double “hot spot” (HS) is inserted, i.e., two mutually symmetric sites carrying linear gain and cubic nonlinearity. The system can be implemented as an array ...

Spatial solitons supported by localized gain in nonlinear optical waveguides
We introduce a modification of the complex Ginzburg-Landau (CGL) equation with background linear loss and locally applied gain. The equation appertains to laser cavities based on planar waveguides, and also to...
