Abstract:

A novel photonic crystal fiber Bragg grating (PCFBG) filled with magnetic fluid (MF) is proposed. The magnetically induced tuning properties of the MF-filled PCFBG were investigated by multipole method, coupled-mode theory and transfer matrix method. The spectral characteristics and mode coupling behaviors of the MF-filled PCFBGs are figured out and theoretical calculations show that the reflection spectrum of the MF-filled PCFBG is sensitive to magnetic field. The results on the influence of an external magmatic field on reflection spectrum of the MF-filled PCFBG are simulated and preliminary results of magmatic field effects on reflection spectrum of the MF-filled PCFBG are discussed. Measuring-induced shifts of the resonant wavelengths give information about the value of magmatic field. When the wavelength λ = 1550 nm, the duty ratio d/Λ = 0.9, the resonant wavelength decreases from 1545.9 nm to 1540.1 nm as the magnetic field changes from 0 Oe to 300 Oe. Sensitivity is about 0.0193 nm/Oe, and there is a fairly good linearity. This scheme opens up a range of perspective applications of the MFfilled PCFBG for magnetic field sensing.
