The Fizeau’s light birefringence dragging effect is investigated in a moving chiral medium. The effect significantly influences the subluminality, superluminality, phase shift and divergence angle between the circularly polarized birefringent modes. The maximum superluminal group velocity is measured in the range –m/s. The group index and group velocity measured with phase of the control field and phase of the superposition states are in the range and m/sm/s, respectively. The maximum Fizeau’s birefringence dragging coefficient is noted in the range and varies with phases of the applied fields in the range . The birefringent phase uncertainty between the phase shift under dragging and in the absence of the dragging effect is in the range radian. The divergence angle between the two modes is in the range radian. The controlled birefringence phase uncertainty may show significant applications in interferometry, velocimetry and sensitivity.
