Abstract
We proposed a novel optical fiber hydrophone based on the feedback effect of a composite cavity optical fiber laser (CCFL) and a corresponding intensity demodulation scheme. The feedback of the CCFL is introduced by the end face reflection of the single mode optical fiber. The intensity modulation of the CCFL is caused by the modulation of the CCFL feedback.
