On-chip topological nanophotonic devices, which take photons as information carriers with
topological protection during light propagation, have great application potential in the next …

On-chip photonic systems play crucial roles in nanoscience and nanoapplications, but
coupling external light to these subwavelength devices is challenging due to a large mode …

In recent years, topological photonics inspired by electric topological insulators has
promoted extensive research on robust electromagnetic (EM) wave manipulation and new …

Higher-order topological insulators (HOTIs) have attracted considerable attention because
of their topological properties of low-dimensional topological corner states and edge states …

As the field of topological photonics has developed over the past 10 years, it has been
proven that the combination of topology and photons is very beneficial to the design of …

In a Hermitian system, bound states must have quantized energies, whereas free states can
form a continuum. We demonstrate how this principle fails for non-Hermitian systems, by …

Using the trapped rainbow effect to slow down or even stop light has been widely studied.
However, high loss and energy leakage severely limited the development of rainbow …

We present an on-chip filter with a broad tailorable working wavelength and a single-mode
operation. This is realized through the application of topological photonic crystal nanobeam …

Over the recent decade, topological insulators, originating from the condensed matter
physics, have resided at the frontier in the field of acoustics owing to their novel topological …

To keep up with the growing bandwidth demands, photonic integrated circuits (PICs) have
been widely employed in various application scenarios where high capacity and high …
