Broadband Acoustic Vibration Sensor Based on Cladding-Mode Resonance of Double-Cladding Fiber
Abstract We have proposed and demonstrated a double-cladding fiber (DCF) with cladding-mode resonance property for broadband acoustic vibration sensing. Since the fundamental mode in the core waveguide is able to be coupled to LP05 mode in the tube waveguide once the phase-matching condition is fulf...
