Photoacoustic raster scan imaging using an optomechanical ultrasound sensor in silicon photonics

Photoacoustic tomography defines new challenges for ultrasound detection compared to ultrasonography. To address these challenges, a sensitive, small, scalable, and broadband optomechanical ultrasound sensor (OMUS) has been developed. The OMUS is an on-chip optical ultrasound sensor, using optical interferometric ultrasound detection. It...

Sensitive optomechanical ultrasound sensor in a silicon photonic chip towards single-shot photoacoustic imaging with an ultrasound sensor matrix

We propose a new opto-mechanical ultrasound sensor (OMUS) enabled by an innovative silicon photonics waveguide. We present experimental results up to 30 MHz, a 10-sensor array proof-of-concept and our latest findings.
