The term whispering gallery mode (WGM) was first introduced to describe the curvilinear
propagation of sound waves under a cathedral dome. The physical concept has now been …

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

Detection of nanoscale objects is highly desirable in various fields such as early‐stage
disease diagnosis, environmental monitoring and homeland security. Optical microcavity …

The experimental realization of a Kerr frequency comb represented the convergence of
research in materials, physics, and engineering. This symbiotic relationship continues to …

Single-mode lasing in whispering-gallery mode (WGM) microresonators is challenging to
achieve. In bottle microresonators, the highly non-degenerated WGMs are spatially well …

Ionised gas, ie, plasma, is a medium where electrons-ions dynamics are electrically and
magnetically altered. Electric and magnetic fields can modify plasma's optical loss …

One of the frontiers in the field of biosensors is the ability to quantify specific target
molecules with enough precision to count individual units in a test sample, and to observe …

The optical microresonators reviewed in this paper are called bottle microresonators
because their profile often resembles an elongated spheroid or a microscopic bottle. These …

We report on the experimental observation of coherent cavity soliton frequency combs in
silica microspheres. Specifically, we demonstrate that careful alignment of the microsphere …

A review of hollow core whispering gallery resonators (WGRs) is given. After a short
introduction to the topic of whispering gallery resonators we provide a description of …
