Frequency combs (FCs)—spectra containing equidistant coherent peaks—have enabled
researchers and engineers to measure the frequencies of complex signals with high …

Nonlinear optical processes are vital for fields including telecommunications, signal
processing, data storage, spectroscopy, sensing and imaging. As an independent research …

Atomic force microscopy (AFM) was used to study the interfacial rheology of air/water
interfaces by investigating the thermal capillary fluctuations of surfactant-loaded interfaces …

The bulk acoustic modes of liquid droplets, well understood from a theoretical perspective,
have rarely been observed experimentally. Here, we report the indirect observation of …

Liquid droplet whispering-gallery-mode microresonators open a new research frontier for
sensing, optomechanics and photonic devices. At visible wavelengths, where most liquids …

We provide here an overview of passive optical micro-cavities made of droplets in the liquid
phase. We focus on resonators that are naturally created and suspended under gravity …

Lasers rely on stimulated electronic transition, a quantum phenomenon in the form of
population inversion. In contrast, phonon masers,, depend on stimulated Raman scattering …

Liquid drops and vibrations are ubiquitous in both everyday life and technology, and their
combination can often result in fascinating physical phenomena opening up intriguing …

Optofluidic resonators are capable of characterizing various fluidic media. Here, we propose
an optofluidic microbottle resonator (OFMBR) that is applied to generate pendant droplets …

When confined within an optical cavity light can exert strong radiation pressure forces.
Combined with dynamical backaction, this enables important processes, such as laser …
