Topological photonic insulators are photonic quantum metamaterials whose transmission bands and bandgaps are characterized by certain topological invariants, which remain unchanged in the presence of lattice disorders. This resistance to defects has been exploited to realize integrated photonic devices that are tolerant to random variations, such as fabrication-induced imperfections or fluctuations in device operating conditions. While topological photonic insulators have been demonstrated for some applications such as optical delay lines, lasers, and single-photon emitters, the lack of efficient methods for trapping and steering light in a topological photonic lattice has limited their potential applications. Floquet defect mode resonance (FDMR), induced through a perturbation to the periodic Hamiltonian, can form compact, tunable, and high quality factor resonances in a Floquet insulator composed of a 2D lattice of coupled microring resonators. This research focuses on the design and implementation of high quality factor FDMRs on a silicon topological photonic platform and explores their potential applications in nonlinear, quantum, and active silicon photonics. In particular, broadband resonance-enhanced frequency generation was successfully demonstrated using stimulated four-wave mixing and extended to entangled photon-pair generation through spontaneous four-wave mixing. These efforts move topological silicon photonics towards the development of efficient and robust on-chip quantum light sources. Additionally, pn-junctions integrated into the silicon microring lattice allowed for the investigation of modulated FDMR by the plasma effect. Finally, the coupling of many FDMR together was explored to route light across the TPI lattice. These nonlinear and active devices broaden the scope of applications of topological photonic insulators for realizing robust photonic integrated circuits and quantum photonic circuits that are tolerant to device parameter variations.
