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…
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…
Strip-Loaded Nanophotonic Interfaces for Resonant Coupling and Single-Photon Routing
Katharine Snow, Fatemeh Moradiani, Hamidreza Siampour
We report on the design and simulation of strip-loaded nanophotonic interfaces aimed at improving resonant coupling and photon routing efficiency. In our design, the guided mode is…
Observation of large spontaneous emission rate enhancement of quantum dots in a broken-symmetry slow-light waveguide
Hamidreza Siampour, Christopher O'Rourke, Alistair J. Brash +7
Quantum states of light and matter can be manipulated on the nanoscale to provide a technological resource for aiding the implementation of scalable photonic quantum technologies […
Unidirectional single-photon emission from germanium-vacancy zero-phonon lines: Deterministic emitter-waveguide interfacing at plasmonic hot spots
Hamidreza Siampour, Ou Wang, Vladimir A. Zenin +10
Striving for nanometer-sized solid-state single-photon sources, we investigate atom-like quantum emitters based on single germanium vacancy (GeV) centers isolated in crystalline na…
On-chip excitation of single germanium-vacancies in nanodiamonds embedded in plasmonic waveguides
Hamidreza Siampour, Shailesh Kumar, Valery A. Davydov +3
Monolithic integration of quantum emitters in nanoscale plasmonic circuitry requires low-loss plasmonic configurations capable of confining light well below the diffraction limit.…
Chip-integrated plasmonic cavity-enhanced single nitrogen-vacancy center emission
Hamidreza Siampour, Shailesh Kumar, Sergey I. Bozhevolnyi
High temporal stability and spin dynamics of individual nitrogen-vacancy (NV) centers in diamond crystals make them one of the most promising quantum emitters operating at room tem…
Nanofabrication of Plasmonic Circuits Containing Single Photon Sources
Hamidreza Siampour, Shailesh Kumar, Sergey I. Bozhevolnyi
Nanofabrication of photonic components based on dielectric-loaded surface plasmon-polariton waveguides (DLSPPWs) excited by single nitrogen vacancy (NV) centers in nanodiamonds is…
