A simple and compact interferometer structure based on no-core fiber (NCF) and fiber Bragg grating (FBG) is proposed for simultaneous measurement of surrounding refractive index (SRI) and temperature. Two methods of measurement may be used here: 1) the sensing information can be analyzed by the wavelengths shift of the NCF-based interferometer and one arbitrarily FBG-reflected modes, or 2) they can be solely extracted through both wavelength and power of each FBG reflected mode.
