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…
