摘要:The intensity response of Distributed-Feedback fiber laser (DFB-FL) to external acoustic excitation has been investigated theoretically and experimentally. The transfer function for external acoustic excitation modulation has been obtained, and the intensity response characteristics of DFB-FL to external acoustic excitation are described by simulation. Through experiments we observe a signal of 16.5 kHz with 25 dB in the DFB-FL RIN spectrum as the external acoustic pressure is 10.25 Pa. The signal power obtained in time domain is 0.033 mu W and acoustic pressure sensitivity which is calculated as -169.8 dB re mu W/mu Pa at 16.5 kHz, which confirms that DFB-FL has the potential to be used as an intensity-type acoustic sensor.
