Rare Earth-Doped Microfiber Bragg Grating Refractive Index Sensor With Self-Photothermal Manipulation

Rare Earth-Doped Microfiber Bragg Grating Refractive Index Sensor With Self-Photothermal Manipulation

We demonstrate a microfiber Bragg grating as the reflective refractometer with the function of self-photoheating. The rare earth-doped fiber provides not only the photosensitivity to the UV modulation but also the effective pump laser absorption and photoheating conversion. The rare earth-doped micr...
