Abstract

We investigate the effect of breaking the parity of a photonic crystal waveguide designed to have odd and even modes intersecting inside the photonic bandgap. The complete study on the wavefields properties of the resulting bonding modes uncovers that the transverse spin and orbital parts of the angular momentum couple in the very slow-light regime by the means of their local currents. This leads to a sub-bandgap opening between bands characterized by distinct organizations of this spin-orbit coupling at the nano-scale.
