A novel polarimetric referencing scheme is proposed in order to correct measurements in a D‐fiber methane gas sensor. The technique makes use of the polarization‐maintaining property of the D‐fiber. Theoretical analysis of the scheme is carried out using a semivectorial polarized finite‐difference method. Results show that the referencing technique can be applied to a wide range of both aqueous and gaseous species, as it does not depend on the absorption coefficient of the absorber, but only on the birefringence properties of the waveguide. © 1995 John Wiley & Sons, Inc.
