提出了一种基于光纤布拉格光栅（FBG）与一段无芯光纤（NCF）集成的新型折射率光纤激光传感器，并进行了实验验证。光纤激光器的振荡波长仅由光纤光栅的中心波长决定，对周围的折射率不敏感。然而，光纤激光器的输出功率随着SRI而变化，这是因为激光输出被NCF中的多模干涉（MMI）效应形成的带通滤波器（BPF）的边缘滤波，该带通滤波器对SRI敏感。通过测量输出功率的变化，可以实现具有成本效益的功率检测RI传感器。光纤激光传感器在折射率为1.333-1.4076的范围内，灵敏度为113.73dB/RIU，与折射率呈线性关系。
A novel refractive index fiber laser sensor based on a fiber Bragg grating (FBG) integrated with a section of no-core fiber (NCF) is proposed and experimentally demonstrated. The oscillating wavelength of the fiber laser is only decided by the central wavelength of the FBG that is insensitive to the surrounding refractive index (SRI). However, the output power of the fiber laser varies with the SRI because the laser output is filtered by the edge of the bandpass filter (BPF) formed by the multimode interference (MMI) effect in the NCF, which is sensitive to the SRI. By measuring the variation of the output power, a cost-effective power detection RI sensor could be realized. The fiber laser sensor has a linear relationship with SRI and a sensitivity of 113.73 dB/RIU in the RI range of 1.333-1.4076.
