Nonlinear Optics in Guided Geometries - Abstract
Konotop, Vladimir
It is shown that nonlinear optical cavities under periodic modulations can exhibit dissipative Bloch waves. This can be achieved by a proper choice of the injected external field that must compensate for losses and match with the modulation period. Dissipative Bloch waves, unlike their conservative counterparts, emerge in non-equilibrium systems and hence correspond to attracting solutions. This makes it possible to experimentally visualize the band structure of the cavity medium. As an illustration of this phenomenon we perform analytical investigations on a degenerate optical parametric oscillator with a modulated transverse refractive index.
