Near-Field Characterisation of Guided Modes in WS2 Nanobeams and Quasi-Bulk Crystals
Zara S. Taylor, Luke M. Hallacy, Xuerong Hu +7
The exceptionally high in-plane refractive index, low sub-bandgap absorption, and strong optical anisotropy of WS2 make it a promising material platform for next-generation integra…
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…
Routing single photons with quantum emitters coupled to nanostructures
Mateusz Duda, Nicholas J. Martin, Eve O. Mills +2
Quantum emitters coupled to nanophotonic structures are an excellent platform for controllable single-photon scattering. The tunable light-matter interaction enables the constructi…
Controlling coherence between waveguide-coupled quantum dots
D. Hallett, J. Wiercinski, L. Hallacy +10
We present a novel waveguide design that incorporates a split-diode structure, allowing independent electrical control of transition energies of multiple emitters over a wide range…
Electro-mechanically tunable, waveguide-coupled photonic-crystal cavities with embedded quantum dots
Luke A. F. Brunswick, Luke Hallacy, René Dost +3
On-chip micro-cavities with embedded quantum emitters provide an excellent platform for high-performance quantum technologies. A major difficulty for such devices is overcoming the…
Waveguide Excitation and Spin Pumping of Chirally Coupled Quantum Dots
Savvas Germanis, Xuchao Chen, René Dost +7
We report on an integrated semiconductor chip where a single quantum dot (QD) is excited in-plane via a photonic-crystal waveguide through its nearest p-shell optical transition. T…
