摘要

Abstract

Ultrasound sensors play an important role in biomedical imaging

industrial nondestructive inspection

etc. Traditional ultrasound sensors that use piezoelectric transducers face limitations in sensitivity and spatial resolution when miniaturized

with typical sizes at the millimeter to centimeter scale. To overcome these challenges

optical ultrasound sensors have emerged as a promising alternative

offering both high sensitivity and spatial resolution. In particular

ultrasound sensors utilizing high-quality factor (

) optical microcavities have achieved unprecedented performance in terms of sensitivity and bandwidth

while also enabling mass production on silicon chips. In this review

we focus on recent advances in ultrasound sensing applications using three types of optical microcavities: Fabry-Perot cavities

π-phase-shifted Bragg gratings

and whispering gallery mode microcavities. We provide an overview of the ultrasound sensing mechanisms employed by these microcavities and discuss the key paramet

ers for optimizing ultrasound sensors. Furthermore

we survey recent advances in ultrasound sensing using these microcavity-based approaches

highlighting their applications in diverse detection scenarios

such as photoacoustic imaging

ranging

and particle detection. The goal of this review is to provide a comprehensive understanding of the latest advances in ultrasound sensing with optical microcavities and their potential for future development in high-performance ultrasound imaging and sensing technologies.
