Optical resonator analog of a two-dimensional topological insulator
A lattice of optical ring resonators can exhibit a topological insulator phase, with the role of spin played by the direction of propagation of light within each ring. Unlike the system studied by Hafezi et al., [Nat. Phys. 7 907 (2011)] topological protection is achieved without fine-tuning the int...
