| contents | Various optical ultrasound microsensors have been developed with size ranging from tens to hundreds of micrometers. However, it becomes challenging to further minimize these sensors' size. In this work, we proposed a method that use a tapered fiber-based micro-waveguide (TFMW) attaching to the optical microsensor to bypass this challenge. The TFMW not only serves as the waveguide to transport ultrasound, but can also deliver light and actively excite ultrasound. In this study, we proposed the design and analyzed its performance using theoretical analysis and simulation. |
