Abstract
In this talk, I will provide an overview of the field of topological photonics, with special emphasis on the photonic emulation of the canonical quantum topological phases such as the Hall, spin-Hall, and valley-Hall phases. I will then describe how such heterogeneous photonic topological phases can be integrated and used for developing novel devices such as compact circulators and delay lines. Experimental results demonstrating reflectionless transport of topologically protected edge states will be presented. I will also discuss how the ideas from topological photonics can be used for complete reimagining of the architectures of photonic devices such as add/drop filters and delay lines. Future directions towards bringing topological photonics to nanoscale will also be discussed.
