Active chiral control of GHz acoustic whispering-gallery modes (2017)
Journal Article

We selectively generate chiral surface-acoustic whispering gallery modes in the gigahertz range on a microscopic disk by means of an ultrafast time-domain technique incorporating a spatial light modulator. Active chiral control is achieved by making... Read More about Active chiral control of GHz acoustic whispering-gallery modes.

Cell imaging by phonon microscopy: sub-optical wavelength ultrasound for non-invasive imaging (2017)
Journal Article

The mechanical properties of cells play an important role in cell function and behavior. This paper presents recent developments that have enabled the use of laser-generated phonons (ultrasound) with sub-optical wavelengths to look inside living cell...

Size characterisation method and detection enhancement of plasmonic nanoparticles in a pump–probe system (2017)
Journal Article

The optical resonance of metal nanoparticles can be used to enhance the generation and detection of their main vibrational mode. In this work, we show that this method allows the accurate characterisation of the particle’s size because the vibrationa...

Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces (2017)
Journal Article

Recent years have heralded the introduction of metasurfaces that advantageously combine the vision of sub-wavelength wave manipulation, with the design, fabrication and size advantages associated with surface excitation. An important topic within met... Read More about Enhanced sensing and conversion of ultrasonic Rayleigh waves by elastic metasurfaces.

Orientation imaging of macro-sized polysilicon grains on wafers using spatially resolved acoustic spectroscopy (2017)
Journal Article

Due to its economical production process polysilicon, or multicrystalline silicon, is widely used to produce solar cell wafers. However, the conversion efficiencies are often lower than equivalent monocrystalline or thin film cells, with the structur...
