Nonlinear photonic disclination states by Boquan Ren, Hongguang Wang, Yaroslav V. Kartashov, Yongdong Li, Yiqi Zhang

“…Here, we present the first example of the nonlinear photonic disclination state bifurcating from its linear counterpart in the disclination lattice with a pentagonal or heptagonal core. We show that nonlinearity allows us to tune the location of the disclination states in the bandgap and notably affects their shapes. …”
