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 …

Brillouin microscopy is an emerging optical elastography technique capable of assessing
mechanical properties of biological samples in a three-dimensional, all-optical and …

In the past decade there has been a surge in research at the boundary between photonics
and phononics. Most efforts have centred on coupling light to motion in a high-quality optical …

Photonic bound states in the continuum (BICs) have recently been studied in various
systems and have found wide applications in sensors, lasers, and filters. Applying BICs in …

Stimulated Brillouin scattering (SBS), as one type of third-order nonlinear optics effect, is
extensively exploited and rapidly developed in the field of lasers and optoelectronics. A …

A theoretical and experimental study on the response of Brillouin scattering in multi-core
optical fibers (MCF) under different curving conditions is presented. Results demonstrate …

Silicon nitride (Si 3 N 4) has emerged as a promising material for integrated nonlinear
photonics and has been used for broadband soliton microcombs and low-pulse-energy …

Micro/nanofibres (MNFs) are optical fibres with diameters close to or below the vacuum
wavelength of visible or near-infrared light. Due to its wavelength-or sub-wavelength scale …

The interaction between light and mesoscopic mechanical degrees of freedom has been
investigated under various perspectives, from spectroscopy in condensed matter, optical …
