Chiral light-matter interaction [1] in optoelectronic devices such as Glide Plane Photonic Crystal Waveguides (GPW) provide an ultimate environment to facilitate on-chip, strong interaction between photons and the spin of charge carriers confined in quantum dot (QD) excitons, opening a new era of scalable, photon-mediated quantum spin network [2]. Here we present a specially designed spin-photon interface [3,4] where the propagation direction of emitted photons is associated with the exciton spin via spin-orbit coupling. The device consists of a p-i-n diode structure that enables the spectral tunability of single photon emitters embedded in a suspended GPW membrane. We focus on emitters located spatially at the chiral points and spectrally inside the slow-light region, where both strong Purcell enhancement and high chirality criteria are satisfied for a single QD (as is shown in Fig.1). A remote excitation method is employed which dramatically enhances the directional contrast under a linearly polarised pump. We show that the combination of GPWs with in-plane p-shell excitation enables an efficient initialisation mechanism of the circularly polarised states. Additionally, this approach facilitates the coherent control on-chip and readout of quantum information encoded in these spins [5].
