Paper Abstract

In this paper, temperature compensated microfiber Bragg grating (mFBG) is realized by use of a liquid with a negative thermo-optic coefficient. The effects of grating elongation and the index change of silica glass are compensated by the liquid through evanescent-field interaction. As a result, the reflective wavelength shifts by only 30 pm when the temperature varies from 15 to 60°C. The proposed method is promising due to the compactness and high flexibility of the device.
