Physical systems with topological properties are robust against disorder. However,
implementing them in integrated photonic devices is challenging because of the various …

The Eigenstate Thermalization Hypothesis (ETH) has been highly influential in explaining
thermodynamic behavior of closed quantum systems. As of yet, it is unclear whether and …

Coupled cavities are of interest as they expose qualitatively new effects, such as non-
Hermitian properties, which are beyond the possibilities of individual cavities. Here, we …

The practical application of integrated gyroscopes in engineering has not yet been fully
realized due to the linear correlation between the Sagnac effect and dimensions. In recent …

We propose an N-order generalized temporal coupled mode theory (g-TCMT) model, which
provides spectral analysis over a wider range for coupled optical resonators with arbitrary …

Backscattering in micro-ring cavities induces mode mixing and limits device performance.
Existing methods to mitigate backscattering often involve complex fabrication processes or …

We develop a 4× 4-matrix model based on temporal coupled mode theory (TCMT) to
elucidate the intricate energy exchange within a non-Hermitian, resonant photonic structure …

Chirality, one of the universal phenomena in physics, forms the playground for fascinating
phenomena in modern electromagnetism and industrial applications. Within the rapidly …

Otical gyroscopes in microcavity platforms have obtained many attentions for their vast
applications. For Sagnac effect enhancement, Exceptional Surface (ES) concept holds …
