✦ Synopsis

In contrast to pre¨ious bulk optic approaches, this letter describes a no¨el all-fiber polarimeter for chemical sensing using D-fiber. The polarimeter is a single-fiber sensor, and is less sensiti¨e to en¨ironmental fluctuation in comparison with the two-fiber interferometric sensor. Theoretical sensiti¨ity calculations are de¨eloped using a finitedifference method in order to pro¨ide design parameters to assist in the implementation of the polarimeter. The o¨erall retardation stability of this D-fiber polarimeter was measured to be 0.35 = 2 radrmrK, and ( the phase change corresponding to the antibody protein ␣ HCG and ) ␣ HSA monolayers was 0.42 = 2 , demonstrating the benefits of the technique for use in biotechnological applications.
