摘要:

提出了一种利用半导体激光器光源的电流调制对无源光纤光栅法布里-珀罗谐振腔进行远程解调的方法。由于RF振幅和频率调制的存在,它是超灵敏的Pound-Drever-Hall激光频率锁定技术的变体。我们证明,电流调制和干涉解调消除了对相位调制器的传感架构的需要。

英文摘要:

We present a method for remote interrogation of passive fiber Bragg grating Fabry-Perot resonators, employing current modulation of the diode laser source. With the presence of both RF amplitude and frequency modulation, it is a variant of the ultra-sensitive Pound-Drever-Hall laser frequency locking technique. We demonstrate that current modulation and interferometric demodulation removes the need for a phase modulator in the sensing architecture.
