Nonlinear control of photonic higher-order topological bound states in the continuum
Zhichan Hu, Domenico Bongiovanni, Dario Jukić +7
Higher-order topological insulators (HOTIs) are recently discovered topological phases, possessing symmetry-protected corner states with fractional charges. An unexpected connectio…
Free-space Realization of Tunable Pin-like Optical Vortex Beams
Domenico Bongiovanni, Denghui Li, Michail Goutsoulas +6
We demonstrate, both analytically and experimentally, free-space pin-like optical vortex beams (POVBs).Such angular-momentum-carrying beams feature tunable peak intensity and under…
Dynamically Emerging Topological Phase Transitions in Nonlinear Interacting Soliton Lattices
Domenico Bongiovanni, Dario Jukić, Zhichan Hu +6
We demonstrate dynamical topological phase transitions in evolving Su-Schrieffer-Heeger (SSH) lattices made of interacting soliton arrays, which are entirely driven by nonlinearity…
