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…
Stark Tuning and Charge State Control in Individual Telecom C-Band Quantum Dots
N. J. Martin, A. J. Brash, A. Tomlinson +12
Telecom wavelength quantum dots (QDs) are emerging as a promising solution for generating deterministic single photons compatible with existing fiber optic infrastructure. Emission…
Chiral Quantum Optics with Scalable Quantum Dot Dimers
L. Hallacy, D. Hallett, A. Fenzl +8
We present a scalable method for electrically tuning multiple spatially separated quantum dots embedded in photonic crystal waveguides. Ion implantation into the top p-doped layer…
Purcell-Enhanced, Directional Light-Matter Interaction in a Waveguide-Coupled Nanocavity
Nicholas J. Martin, Dominic Hallett, Mateusz Duda +9
We demonstrate electrically tunable, spin-dependent, directional coupling of single photons by embedding quantum dots (QDs) in a waveguide-coupled nanocavity. The directional behav…
