Quantum optics with near lifetime-limited quantum-dot transitions in a nanophotonic waveguide
Henri Thyrrestrup, Gabija Kiršanskė, Hanna Le Jeannic +13
Establishing a highly efficient photon-emitter interface where the intrinsic linewidth broadening is limited solely by spontaneous emission is a key step in quantum optics. It open…
Spin-photon interface and spin-controlled photon switching in a nanobeam waveguide
Alisa Javadi, Dapeng Ding, Martin Hayhurst Appel +13
Access to the electron spin is at the heart of many protocols for integrated and distributed quantum-information processing [1-4]. For instance, interfacing the spin-state of an el…
Narrow optical linewidths and spin pumping on charge-tunable, close-to-surface self-assembled quantum dots in an ultra-thin diode
Matthias C. Löbl, Immo Söllner, Alisa Javadi +9
We demonstrate full charge control, narrow optical linewidths, and optical spin pumping on single self-assembled InGaAs quantum dots embedded in a thin diode str…
Numerical modelling of the coupling efficiency of single quantum emitters in photonic-crystal waveguides
Alisa Javadi, Sahand Mahmoodian, Immo Söllner +1
Planar photonic nanostructures have recently attracted a great deal of attention for quantum optics applications. In this article, we carry out full 3D numerical simulations to ful…
Deterministic enhancement of coherent photon generation from a nitrogen-vacancy center in ultrapure diamond
Daniel Riedel, Immo Söllner, Brendan J. Shields +5
The nitrogen-vacancy (NV) center in diamond has an optically addressable, highly coherent spin. However, an NV center even in high quality single-crystalline material is a very poo…
Indistinguishable and efficient single photons from a quantum dot in a planar nanobeam waveguide
Gabija Kiršanskė, Henri Thyrrestrup, Raphaël S. Daveau +16
We demonstrate a high-purity source of indistinguishable single photons using a quantum dot embedded in a nanophotonic waveguide. The source features a near-unity internal coupling…
Engineering chiral light--matter interaction in photonic crystal waveguides with slow light
Sahand Mahmoodian, Kasper Prindal-Nielsen, Immo Söllner +2
We design photonic crystal waveguides with efficient chiral light--matter interfaces that can be integrated with solid-state quantum emitters. By using glide-plane-symmetric wavegu…
Deterministic Single-Phonon Source Triggered by a Single Photon
Immo Söllner, Leonardo Midolo, Peter Lodahl
We propose a scheme that enables the deterministic generation of single phonons at GHz frequencies triggered by single photons in the near infrared. This process is mediated by a q…
Single-photon nonlinear optics with a quantum dot in a waveguide
A. Javadi, I. Söllner, M. Arcari +9
Strong nonlinear interactions between photons enable logic operations for both classical and quantum-information technology. Unfortunately, nonlinear interactions are usually feebl…
Deterministic photon-emitter coupling in chiral photonic circuits
Immo Söllner, Sahand Mahmoodian, Sofie Lindskov Hansen +9
The ability to engineer photon emission and photon scattering is at the heart of modern photonics applications ranging from light harvesting, through novel compact light sources, t…
Near-unity coupling efficiency of a quantum emitter to a photonic-crystal waveguide
M. Arcari, I. Söllner, A. Javadi +8
A quantum emitter efficiently coupled to a nanophotonic waveguide constitutes a promising system for the realization of single-photon transistors, quantum-logic gates based on gian…
Nonuniversal intensity correlations in 2D Anderson localizing random medium
Pedro David García, Søren Stobbe, Immo Söllner +1
Complex dielectric media often appear opaque because light traveling through them is scattered multiple times. Although the light scattering is a random process, different paths th…
