چکیده انگلیسی
We proposed and experimentally demonstrated a miniature optical fiber temperature sensor consisting of a seven core fiber (SCF) and a few mode fiber (FMF). The device is fabricated by splicing a section of FMF with a segment of SCF to form a FMF-SCF based sensing structure, and during the FMF region, few modes can be excited and will propagate within the SCF. In experiment, the proposed device has good quality interferometric spectra, and the highest extinction ratio of 27â¯dB was achieved. When the temperature increases from room temperature to 110â¯Â°C, the temperature response properties of the sensor have been investigated, the wavelength sensitivity of about 91.8â¯pm/°C and the amplitude sensitivity of about 1.57â¯Ãâ¯10â2â¯a.u./°C are obtained, respectively. Due to its easy and controllable fabrication, the sensor can be a suitable candidate in temperature sensing applications.
