Nonlinear light propagation in cholesteric liquid crystals with a helical Bragg microstructure
Yikun Liu, Shenhe Fu, Xing Zhu +7
Nonlinear optical propagation in cholesteric liquid crystals (CLC) with a spatially periodic helical molecular structure is studied experimentally and modeled numerically. This per…

Double symmetry breaking of solitons in one-dimensional virtual photonic crystals
Yongyao Li, Boris A. Malomed, Mingneng Feng +1
We demonstrate that spatial solitons undergo two consecutive spontaneous symmetry breakings (SSBs), with the increase of the total power, in nonlinear photonic crystals (PhCs) buil…

Arrayed and checkerboard optical waveguides controlled by the electromagnetically-induced transparency
Yongyao Li, Boris A. Malomed, Mingneng Feng +1
We introduce two models of quasi-discrete optical systems: an array of waveguides doped by four-level N-type atoms, and a nonlinear checkerboard pattern, formed by doping with thre…
