(a) Calculated sensitivity versus magnetic field strength in the range from 0 to 200 mT; (b) Measured wavelength shift of the selected transmission dip (at λ 0 = 1544.48 nm, PMF length 75 cm) against increasing magnetic field from 0 to 200 mT (red) and decreasing back to 0 mT (blue); (c) Measured wavelength shift of the selected transmission dip (at λ 0 = 1554.88 nm, PMF length 20 cm) against increasing magnetic field from 0 to 200 mT.
