We use the superposition of three probes fields to modify the rotatory photon drag by strength and phases of the applied fields. Subluminal propagation is tuned to superluminal propagation with strength, phases of control field and superposition states. We measure a group index of \(\pm \,2000\) with phases of the control fields and superposition states. The group velocity is modified to \(\pm \,1.5\times 10^5\) m/s in the medium. We investigate the rotary photon drag in the region positive and negative group velocity regions. Significant tunability of rotary photon drag is reported with the phases and strength of applied fields and superposition states. We note a maximum of \(\pm \,5\) micro-radians rotary photon drag in the medium. The significant tunability of photon drag from positive to negative values in micro-radians shows potential application in the spacial modes imaging coding.

我们使用三个探针场的叠加，通过施加场的强度和相位来修改旋转光子阻力。腔内传播被调整为具有强度，控制场相位和叠加状态的超腔传播。我们用控制场和叠加状态的相位来测量\（\ pm \，2000 \）的组索引。 在介质中，组速度被修改为\（\ pm \，1.5 \ times 10 ^ 5 \） m / s。我们研究正向和负向群速度区域中的旋转光子阻力。报告了旋转光子阻力的显着可调性，以及所施加场的相位和强度以及叠加状态。我们注意到最大为\（\ pm \，5 \）微弧度旋转光子在介质中拖动。微弧度中光子阻力从正值到负值的显着可调性显示了在空间模式成像编码中的潜在应用。
