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

Losses are generally undesired in most nanophotonic devices except for some applications such as photothermal conversion because high losses can result in reduced resonance quality. A lot of efforts have thus been made to achieve high-quality resonan
