Tunable Topological Features in Microring Arrays

Topological features can arise when you combine materials or lattices of different configurations at the interface. Individual
elements of the lattice can be engineered to select modes which do not propagate into the rest of the system (by splitting them),
and the rest would be able to, using Floquet optical ring resonators.
We propose to study a different scheme of a photonic topological insulator, one which would allow us to tailor which modes are
protected by topology, and which ones are not. In essence, this could be akin to changing discretely between one kind of system
(i.e, an insulator) to another (a conductor). This would allow us to effectively change the system’s behavior without changing the
geometry in real-time, relying only on the wavelength of the selected mode(s).
