Optical biosensors are frontrunners for the rapid and real-time detection of analytes,
particularly for low concentrations. Among them, whispering gallery mode (WGM) resonators …

Silicon Photonics, the technology where optical devices are fabricated by the mainstream
microelectronic processing technology, was proposed almost 30 years ago. I joined this …

The intriguing and anomalous optical characteristics of exceptional points (EPs) in optical
resonators have attracted significant attention. While EP-related phenomena have been …

The reflectionless coherent light transport in the coupled resonator array is investigated in
the presence of intra-resonator intermodal coupling between the clockwise and …

We propose and numerically analyze a multiple Fano resonance device with high quality (Q)
factor and high modulation depth based on a metal-insulator-metal (MIM) waveguide …

Exceptional points, where eigenvalues and eigenvectors coalesce, impact the behavior of
different photonics components that show, eg, enhanced sensing, coherent perfect …

We report on the demonstration of an effective, nonlinearity-induced nonreciprocal behavior
in a single nonmagnetic multi-mode Taiji resonator. Nonreciprocity is achieved by a …

Non-Hermitian physics has found a fertile ground in optics. Recently, the study of mode
coalescence, ie, exceptional points, has led to the discovery of intriguing and …

It is known that the Kramers-Kronig (KK) relation between real and imaginary parts of the
optical susceptibility in the frequency domain can also be realized in the space domain, as …

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