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…

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…

Nonlinear Quantum Optics at a Topological Interface Enabled by Defect Engineering
L. Hallacy, N. J. Martin, M. Jalali Mehrabad +11
The integration of topology into photonics has generated a new design framework for constructing robust and unidirectional waveguides, which are not feasible with traditional photo…
