After submitting this manuscript we became aware of the work of Tavrov et al. , in which they use the geometric spin redirection phase due to out-of-plane propagation of light to realize an achromatic π-phase shift between the two beams of an astronomical interferometer for "nulling interferometry." In our judgement, the linear phase shift between the beams for circular polarization shown in Fig. 2(a) and the highly nonlinear phase shift for linear polarization shown in Fig. 2(b) of their paper correspond approximately to the curves A and C shown in Fig. of this paper.

When the Jones matrix of a halfwave plate is written without the factor i as done in and in some texbooks on optics, it implies an isotropic phase factor exp(±iπ/2) multiplying the SU(2) part. This must be removed before applying the considerations of Section .
