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…

Collecting single photons from a cavity-coupled quantum dot using an adiabatic tapered fiber
Anatole Bach, Antoine Chapuis, Corentin Morin +9
We demonstrate efficient in-plane optical fiber collection of single photon emission from quantum dots embedded in photonic crystal cavities. This was achieved via adiabatic coupli…
