A submicrometre silicon-on-insulator resonator for ultrasound detection

The widely available silicon-on-insulator technology is used to develop a miniaturized ultrasound detector, which is 200 times smaller than the wavelengths of sound that it can detect.

Bragg grating etalon-based optical fiber for ultrasound and optoacoustic detection

The authors embed a micro-resonator in a 10 µm core fiber, which enables ultrasound wave detection with large bandwidth and small aperture. This facilitates high-resolution optoacoustic (photoacoustic) imaging and ultrasonography.

Sensitive, small, broadband and scalable optomechanical ultrasound sensor in silicon photonics

An optical ultrasound sensor based on a CMOS-compatible split-rib waveguide is demonstrated, offering high sensitivity, broadband detection (measured 3–30 MHz), small size (20 μm) and scalability to a fine-pitch matrix.
