普通单模全光纤化水听器及其驱动电路设计

Design of single-mode all-fiber hydrophone and its drive circuit

  • 摘要: 提出了一种普通单模全光纤化水听器及其驱动电路的设计方法。选择了传输波长为1550nm的单模光纤,采用多量子经阱分布反馈(multi-quantum well distributed feed back, MQW-DFB)半导体激光器作为系统光源,选用MAX3263和MAX038分别设计激光驱动器和高性能正弦波信号发生器,用InGaAs PIN作为光电探测器。实验测试表明:设计的光纤水听器的灵敏度比标准水听器(压电型)高50dB~60dB(在1kHz~30kHz范围)。

     

    Abstract: The design method of the common single-mode all-fiber (SMF) hydrophone and its drive circuit is provided. During the process of the design, SMF whose transmission wavelength is 1550nm was chosen,the MQW-DFB(multiquantum well distributed feed back)semiconductor laser was taken as the light source, MAX3263 and MAX038 were selected to design the laser driver and high-performance sine-wave signal generator, respectively, and InGaAs PIN was taken as the optoelectronic detector. The experiments indicate that the sensitivity of the fiber hydrophone presented in this paper is higher than that of the standard hydrophone (piezoelectricity type) by 50dB~60dB(1kHz~30kHz).
