Optical whispering-gallery mode (WGM) microresonators, confining resonant photons in a
microscale volume for long periods of time, strongly enhance light-matter interactions …

High-and ultrahigh-Q whispering-gallery mode resonators have the capability to trap
photons by total internal reflection for a duration ranging from nanoseconds to milliseconds …

Biosensing relies on the detection of molecules and their specific interactions. It is therefore
highly desirable to develop transducers exhibiting ultimate detection limits. Microcavities are …

Stimulated Brillouin scattering is a fundamental interaction between light and travelling
acoustic waves and arises primarily from electrostriction and photoelastic effects, with an …

Radio-frequency communication systems have long used bulk-and surface-acoustic-wave
devices supporting ultrasonic mechanical waves to manipulate and sense signals. These …

Surface acoustic waves (SAWs) are electro-mechanical waves that form on the surface of
piezoelectric crystals. Because they are easy to construct and operate, SAW devices have …

“Cavity-optomechanics” aims to study the quantum properties of mechanical systems. A
common strategy implemented in order to achieve this goal couples a high finesse photonic …

We review recent progress in inducing and harnessing stimulated Brillouin scattering (SBS)
in integrated photonic circuits. Exciting SBS in a chip-scale device is challenging due to the …

New developments in the microrheology of complex fluids are considered. Firstly the
requirements for a simple modern particle tracking microrheology experiment are …

The analysis of chemical species is one of the most fundamental and long-standing
challenges in fiber-optic sensors research. Existing sensor architectures require a spatial …
