Observation of Electrically Tunable Chirality Inversion in a Slow-Light Waveguide

Xuchao Chen, Savvas Germanis, Nicholas J. Martin +8

We identify chiral inversion points in slow-light, glide-plane-symmetric, photonic-crystal waveguides, defined as fixed locations where the local optical chirality changes sign ove…

Flat-band compactons in a two-dimensional driven-dissipative Lieb lattice

Seth Lovett, Paul M. Walker, Anthony Ellul +3

We experimentally study the effect of inter-particle interactions on the flat-band states of a two-dimensional Lieb lattice with drive and dissipation. Exploiting the giant nonline…
