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…
Tunable self-similar Bessel-like beams of arbitrary order
Michael Goutsoulas, Domenico Bongiovanni, Denghui Li +2
We predict that Bessel-like beams of arbitrary integer order can exhibit a tunable self-similar behavior (that take an invariant form under suitable stretching transformations). Sp…
