Robustness against disorder in topological fibre lasers with explicitly broken PT symmetry
Brook Salter, Nathan Roberts, Habib Rostami +2
Fibre lasers realise a large gain medium in a compactly coiled fibre. Disorder due to fabrication can negatively impact the stability of their lasing modes, especially in multi-cor…
Twisted fibre: a photonic topological insulator
Nathan Roberts, Brook Salter, Jack Binysh +2
The breaking and enforcing of symmetries is a crucial ingredient in designing topologically robust materials. While magnetic fields can break time-reversal symmetry to create Chern…
Single-shot measurement of photonic topological invariant
Nathan Roberts, Guido Baardink, Anton Souslov +1
Topological design enables robustness to be engineered into a system. However, a general challenge remains to experimentally characterize topological properties. In this work, we d…
Topological supermodes in photonic crystal fiber
Nathan Roberts, Guido Baardink, Josh Nunn +2
Topological states enable robust transport within disorder-rich media through integer invariants inextricably tied to the transmission of light, sound, or electrons. However, the c…
