Non-Hermitian optics is a burgeoning field at the intersection of quantum physics,
electrodynamics, and nanophotonics. It provides a new perspective of the role of gain and …

We present a comprehensive overview of sensor technology exploiting optical whispering
gallery mode (WGM) resonances. After a short introduction we begin by detailing the …

Electromagnetically induced transparency, as a quantum interference effect to eliminate
optical absorption in an opaque medium, has found extensive applications in slow-light …

Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a
microscale volume for long periods of time, strongly enhance light-matter interactions …

There has been an increasing interest in all-optical analogues of electromagnetically
induced transparency and Autler–Townes splitting. Despite the differences in their …

Optical whispering‐gallery mode (WGM) microcavities featuring ultrahigh Q factors and
small mode volumes enhance significantly the interaction between light and matter …

Electromagnetically induced transparency (EIT) is a quantum interference effect arising from
different transition pathways of optical fields. Within the transparency window, both …

Optical whispering-gallery-mode microresonators with ultrahigh quality factors and small
mode volumes have played an important role in modern physics. They have been …

We experimentally and theoretically clarified that a Fano resonant system based on a
coupled optical cavity has better performance when used as an all-optical switch than a …

We study single-photon scattering via a giant Λ-type atom, where both atomic transitions are
coupled with the modes of a single waveguide at two separated points. The giant-atom …
