Nanotechnology enables in principle a precise mapping from design to device but relied so
far on human intuition and simple optimizations. In nanophotonics, a central question is how …

Microcavities and nanoresonators have the ability to strongly enhance many light–matter-
interaction processes used in various applications in nano-optics. This enhancement is due …

We present a quasinormal-mode (QNM) theory for coupled loss and gain resonators
working in the vicinity of an exceptional point. Assuming linear media, which can be fully …

Localizing light to nanoscale volumes through nanoscale resonators that are low loss and
precisely tailored in spectrum to properties of matter is crucial for classical and quantum light …

As a basic building block, optical resonant cavities (ORCs) are widely used in light
manipulation. They can confine electromagnetic waves and improve the interaction between …

Near-field optics is an exciting frontier of photonics and plasmonics. The tandem of strongly
localized fields and enhanced emission rates offers significant opportunities for wide …

Micro-and nanoresonators, which enable light trapping in small volumes for extended
durations, play a crucial role in modern photonics. The optical response of these resonators …

Low power consumption is of great importance for on-chip optical applications of
nanolasers. To reduce the lasing threshold, a high quality factor and strong Purcell effect are …

In several publications, it has been shown how to calculate the near-or far-field properties for
a given source or incident field using the resonant states, also known as quasi-normal …

We use low-resolution optical lithography joined with solid state dewetting of crystalline,
ultra-thin silicon on insulator (c-UT-SOI) to form monocrystalline, atomically smooth, silicon …
