Abstract A terahertz band temperature and magnetic field sensor based on a magneto-fluid-filled D-type microstructure grating is designed. The high sensitivity measurement of temperature and magnetic field is realized by optimizing the structure. The highest temperature sensitivity is 233.88 pm/°C, and the highest magnetic field sensitivity is up to 214.802 pm/mT. When the overall structure size of the sensor was changed by ±0.1 %, the maximal absolute deviation of temperature or magnetic field sensor are 0.018 pm/℃ and 0.03 pm/Oe. At the same time, the dual-parameter demodulation matrix is used to effectively overcome the crosstalk problem.

A novel micro-structured fiber magnetic field sensor based on magnetic fluid (MF) filling is proposed. The air hole radius in the cladding of fiber is reduced from inner layer to outer layer, and the numerical analysis is performed by the finite element method (FEM). For the [Formula: see text]-pol mode, the proposed sensor has an average sensitivity of 960.61 pm/Oe, and for the [Formula: see text]-pol mode, the average sensitivity can reach 884.85 pm/Oe. The sensor has the advantages of small size and high sensitivity and is competitive in magnetic field sensors.
