| 摘 要： | 本文开展了光学腔内两正交偏振模振幅和相位补偿的实验研究。通过采用特殊腔型和两个λ/2波片,补偿腔内反射镜对水平偏振模和垂直偏振模的反射率差异,使两个偏振模的输出振幅相等。利用一组λ/4-λ/2-λ/4波片补偿光学腔内水平偏振模和垂直偏振模的相位差,使两个模的输出重合。通过上述的振幅和相位补偿方法,可实现任意偏振光经过环形腔后偏振不变,为任意偏振比特在腔内冷原子系综中的高效率高保真度存储提供了实验基础。

| Abstract: | This paper reports the amplitude compensation and phase compensation of two orthogonal polarization models in optical cavity simultaneously.With a special designed cavity and two half wave plates,the reflectivity difference between the two orthogonal polarization models was compensated and the output peak value of two orthogonal polarization models was equal.The phase difference between two orthogonal polarization models in optical cavity was compensated to zero when using a λ/4-λ/2-λ/4 wave plates sequence and two orthogonal polarization models resonated with the cavity simultaneously.By performing amplitude compensation and phase compensation,the polarization of cavity input can be remained after through the cavity.This work provides an experimental foundation for high efficiency and fidelity quantum memory of arbitrary polarization qubits with cold atoms inside optical cavity. |
