Abstract

Photonic crystal waveguides can support polarisation singularities, which are
predicted to be useful in future quantum information applications. For example, C-points
possess local chirality, allowing spin-photon entanglement when a quantum dot is placed at
its location. Photonic crystal waveguides also support slow-light modes, and we have
studied the enhancement of this coupling in the slow-light regime. We have also studied the
practicalities of using such C-points in real world waveguides with disorder.
