Stable localized modes in asymmetric waveguides with gain and loss
It is shown that asymmetric waveguides with gain and loss can support a stable propagation of optical beams. This means that the propagation constants of modes of the corresponding complex optical potential are real. A class of such waveguides is found from a relation between two spectral problems...

| description |
It is shown that asymmetric waveguides with gain and loss can support a stable propagation of optical beams. This
means that the propagation constants of modes of the corresponding complex optical potential are real. A class of
such waveguides is found from a relation between two spectral problems. A particular example of an asymmetric
waveguide, described by the hyperbolic functions, is analyzed. The existence and stability of linear modes and of
continuous families of nonlinear modes are demonstrated. |
