Confinement of light into small volumes has become an essential requirement for photonic
devices; examples of this trend are provided by optical fibers, integrated optical circuits …

Whispering gallery mode (WGM) microresonators, benefitting from the ultrahigh quality (Q)
factors and small mode volumes, could considerably enhance the light-matter interaction …

Abstract The Whispering Gallery Mode (WGM) operates on principles akin to those of
acoustics. It involves an optical micro-cavity with an echo wall structure, where light waves …

We experimentally demonstrate a bow-shaped fiber structure (BFS) fabricated by a simple
knotting method. Interference transmission spectra of output light is observed due to …

We demonstrate experimentally an all-optical switching operation using the Kerr effect in a
silica toroid microcavity. Thanks to the small mode volume and high quality factor of the …

Microresonators are ideal systems for probing nonlinear phenomena at low thresholds due
to their small mode volumes and high quality (Q) factors. As such, they have found use both …

We report a magnetic field sensor based on an optofluidic microbottle resonator (OFMBR)
with whispering gallery mode (WGM) strongly confined in the axial direction, with the hollow …

A larger number of complicated plasmonic nanostructures have been realized to exhibit
Fano interference. In this paper, we demonstrate a simple nanostructure, side coupled …

Nonlinear frequency generation requires high intensity density which is usually achieved
with pulsed laser sources, anomalous dispersion, high nonlinear coefficients or long …

We investigate the whispering gallery modes (WGMs) of self-assembled single
microspheres. They consist of a recently developed highly fluorescent π-conjugated …
