Minimizing the insertion loss of individual components is paramount importance for large-scale photonic integrated circuits. The measured component losses (5-20 dB) crystal waveguides devices are well beyond numerical predictions (< 0.1 dB). additional sum coupling and propagation in waveguides. Mode mismatch deformation suspended structures increase loss. Nanofabrication-related geometric inho...

The second-order topological photonic crystal with 0D corner state provides a new way to investigate cavity quantum electrodynamics and develop nanophotonic devices diverse functionalities.

Nanophotonic waveguides are the building blocks of integrated photonics. To date, while quarter-wave plates (QWPs) are widely used as common components for a wide range of applications in free space, there are almost no reports of Integratable QWPs being able to manipulate the angular momentum (AM) of photons inside nanophotonic waveguides. Here, we demonstrate two kinds of Integratable QWPs re...

The field of nanophotonics has ushered in a new paradigm of light manipulation by enabling deep subdiffraction confinement assisted by metallic nanostructures. However, a key limitation which has stunted a full development of high-performance nanophotonic devices is the typical large losses associated with the constituent metals. Although silver has long been known as the highest quality plasmo...

Topological edge states (TESs), arising from topologically nontrivial phases, provide a powerful toolkit for the architecture design of photonic integrated circuits, since they are highly robust and strongly localized at boundaries topological insulators. It is desirable to be able control TES transport in implementations. Enhancing coupling between TESs finite-size optical lattice capable exch...
