Topological Polarization Beam Splitter with Polarization-Selective Edge States
Shirin Afzal, Amesh Kahloon, Shabir Barzanjeh
The realization of on-chip polarization beam splitters robust to fabrication imperfections remains a key challenge for polarization-sensitive photonic integration. We demonstrate a…
Broadband Resonance-Enhanced Frequency Generation by Four-Wave Mixing in a Silicon Floquet Topological Photonic Insulator
Tyler J. Zimmerling, Shirin Afzal, Vien Van
Floquet topological photonic insulators, whose light transport properties are dictated by the periodic drive sequence of the lattice, provide more flexibility for controlling and t…
Floquet Mode Resonance: Trapping light in the bulk mode of a Floquet topological insulator by quantum self-interference
Shirin Afzal, Vien Van
Floquet topological photonic insulators characterized by periodically-varying Hamiltonians are known to exhibit much richer topological behaviors than static systems. In a Floquet…
Realization of Anomalous Floquet Insulators in Strongly-Coupled Nanophotonic Lattices
Shirin Afzal, Tyler J. Zimmerling, Yang Ren +2
We experimentally realized Floquet topological photonic insulators using a square lattice of direct-coupled octagonal resonators. Unlike previously reported topological insulator s…
