Integrated photonics have received much attention in recent years as there is a concerted effort towards achieving Very-Large-Scale-Integration of optical components. One of the key elements enabling such dense integration is the optical microring resonator, which has found pervasive applications...

Certain materials, like quartz, are electrically polarized when they are strained. This is called the direct piezoelectric effect. It manifests naturally by the appearance of bound electrical charges at the surfaces of strained medium. This is always accompanied by the converse effect, whereby...

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...

Topological photonic insulators (TPIs), a new phase of matter in photonics, have attracted considerable attention due to their unique ability to transport light via topologically-protected edge states that are immune to defect scattering. Among the various potential applications, this property...
