This paper describes an octagonal photonic crystal fiber (OPCF) magnetic field sensor based on the surface plasmon resonance effect. The magnetic fluid is filled into the first layer of air holes of the OPCF, and the Au is coated into the air hole located in the y -direction. The external magnetic f...
