Symmetry breaking and manipulation of nonlinear optical modes in an asymmetric double-channel waveguide
Rujiang Li, Fei Lv, Lu Li +1
We study light-beam propagation in a nonlinear coupler with an asymmetric double-channel waveguide and derive various analytical forms of optical modes. The results show that the s…
Nonlinear suppression of time-reversals in PT-symmetric optical couplers
Andrey A. Sukhorukov, Zhiyong Xu, Yuri S. Kivshar
We reveal a generic connection between the effect of time-reversals and nonlinear wave dynamics in systems with parity-time (PT) symmetry, considering a symmetric optical coupler w…
Complete spectral gap in coupled dielectric waveguides embedded into metal
Wei Liu, Andrey Sukhorukov, Andrey Miroshnichenko +4
We study a plasmonic coupler involving backward (TM_01) and forward (HE_11) modes of dielectric waveguides embedded into infinite metal. The simultaneously achievable contradirecti…
Spatial-Spectral Vortex Solitons in Quadratic Lattices
Zhiyong Xu, Andrey A. Sukhorukov
We predict the existence of spatial-spectral vortex solitons in one-dimensional periodic waveguide arrays with quadratic nonlinear response. In such vortices the energy flow forms…
Vector vortex solitons in nematic liquid crystals
Zhiyong Xu, Noel F. Smyth, Antonmaria A. Minzoni +1
We analyze the existence and stability of two-component vector solitons in nematic liquid crystals for which one of the components carries angular momentum and describes a vortex b…
