We present a novel photonic crystal waveguide, engineered to support broadband modes with circular in-plane polarization. We show experimental evidence that for single-photon emitters with circular dipoles these waveguides act as near-lossless unidirectional photonic reservoirs, where the emission direction is given by the helicity of the dipole. This directional coupling has a strong effect on the scattering of single photons transmitted through the system and we discuss how counter-propagating photons acquire a relative phase of π. Combining this effect with photonic structures that can map a phase to a propagation path, we show how one can create nonreciprocal photonic elements.

Conference Presentations are recordings of oral presentations given at SPIE conferences and published as part of the proceedings. They include the speaker's narration with video of the slides and animations. Most include full-text papers. Interactive, searchable transcripts and closed captioning are now available for most presentations.
