Abstract

We demonstrate that, for suitable trapping one-dimensional Dirac potentials, there exist guided modes exhibiting spin-dependent field distributions, which may give rise to their different coupling efficiency to the radiative continuum or light-matter coupling properties. For leaky open Dirac metasurfaces this should manifest in different transport and radiative properties of modes of opposite spin 3 the non-Hermitian spin-Hall effect. We use silicon nanophotonic metasurfaces that support pseudo-spin degree of freedom as a testing platform to experimentally confirm such spin-dependent non-Hermitian properties of spin-full photonic Dirac waveguides.
