Modern nanotechnology allows one to scale down various important devices (sensors,
chips, fibers, etc.) and thus opens up new horizons for their applications. The efficiency of …

In contrast to a conventional symmetric Lorentzian resonance, Fano resonance is
predominantly used to describe asymmetric-shaped resonances, which arise from the …

We propose and experimentally demonstrate the enhancement in the filtering quality (Q)
factor of an integrated micro-ring resonator (MRR) by embedding it in an integrated Fabry …

Unconventional characteristics of magnetic toroidal multipoles have triggered researchers to
study these unique resonant phenomena by using both 3D and planar resonators under …

Bismuthene, the last and heaviest group-VA elemental two-dimensional material, has
received tremendous interests owing to its advantages in electronic-transport, semimetallic …

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 …

Phase-change chalcogenide alloys, such as Ge_2Sb_2Te_5 (GST), have very different
optical properties in their amorphous and crystalline phases. The fact that such alloys can be …

A dynamically tunable ultra-broadband terahertz perfect metamaterial absorber based on
vanadium oxide (VO_2) is proposed and numerically demonstrated. The excellent …

We propose and demonstrate, by simply inserting an air-hole in the waveguide side-
coupling with a microring resonator (MRR), that the transmission spectrum presents Fano …

With the advantages of high quality factor (Q) and small mode volume, whispering gallery
mode (WGM) microcavities obtain lower detection limits and have been increasingly applied …
