Glide-symmetric waveguide design for guiding and control of spin-carrying photons

We present a nanophotonic design approach for efficient coupling of circularly-polarized photons emitted from Purcellenhanced quantum dots into a single directional waveguide mode. In the approach, a suspended nanobeam waveguide with glidesymmetrical indents is designed and analysed using photonic band diagram and group velocity dispersion.
