Acoustic Sensing Performance Investigation Based on Grooves Etched in the Ring Resonators
Acoustic detection based on optical technology has moved in the direction of high sensitivity and resolution. In this study, an optical waveguide acoustic sensor based on a ring resonator with the evanescent field is proposed. Grooves are introduced into the ring resonators as a direct sensitive str...
