Channeling defect emission through topological Jackiw-Rebbi states in hBN
Hugo Quard, Sergei Nedić, Nika Teran +4
When two photonic structures of different topology are joined, an optical mode appears at their junction. Its existence depends only on this topological difference and not on the p…

Visible Integrated Photonics with Tantalum Pentoxide
Sergei Nedić, Angus Gale, Hugo Quard +3
Developing chip-scale photonic platforms for the visible spectrum is essential for translating next-generation optical technologies. Here, we demonstrate that tantalum pentoxide Ta…

Electron Beam Restructuring of Quantum Emitters in Hexagonal Boron Nitride
Sergei Nedić, Karin Yamamura, Angus Gale +2
Hexagonal boron nitride (hBN) holds promise as a solid state, van der Waals host of single photon emitters for on-chip quantum photonics. The B-centre defect emitting at 436 nm is…
