The ultrasonic response of single mode fibers has been studied in the frequency regimes where the fiber is isotropic and anisotropic. Good agreement has been obtained between analytical and experimental results. Fiber optimization has been achieved by appropriate selections of fiber coatings which can maximize or minimize the fiber sensitivity. Finally, the air acoustic response of several sensing elements has been studied.
