In this article, we theoretically simulated a silicon core-based fiber Bragg grating and applied for temperature and environmental refractive index sensing simultaneously. The sensitivities of the temperature and refractive index were 79.25 $\text{pm}/^{\mathrm{o}}\mathrm{C}$ and -91.24 $\text{dB}/\text{RIU}$, respectively, within a range of the temperature in 0 to 45 ${^\circ C}$ and the refractive index in 1.0 to 1.4. The proposed fiber sensor head can provide a method with simple and high sensitivity for various sensing target.
