海面泡沫信道的波分复用偏振补偿改进方案研究
|
摘要
海面泡沫信道对量子通信中光子的偏振散射提高了偏振误码率。采用波分复用的偏振补偿方案对其进行补偿。在验证波分复用偏振补偿方案可行性的基础上,针对海面泡沫信道中波长间隔带来的偏振误差问题,提出了单参考光误差校准偏振补偿改进方案和双参考光偏振补偿改进方案。分别仿真了不同波长间隔下补偿后信号光的偏向角分布。结果显示,两种方案均可以有效地消除波长间隔带来的影响误差,其中双参考光偏振补偿方案性能更优,补偿效果更明显,但多参考光对实验设备提出更多的要求;波长间隔取值越小,补偿后信号光的偏向角越小,对应的偏振误码率越低。
The influence of the sea foam channel on the polarization scattering of photons in the quantum communication can lead to the increase of the polarization bit error rate.A polarization compensation scheme based on wavelength division multiplexing(WDM)is used to compensate the state of polarization.Based on the feasibility of the WDM polarization compensation scheme,to solve the problem of the polarization errors caused by the wavelength interval in the sea foam channel,we propose a single-reference-pulse error calibration polarization compensation scheme and a double-reference-pulse error calibration polarization compensation scheme.We simulate the deviation angle distribution of the compensated signal pulse under different wavelength intervals.The results show that the two schemes both can effectively eliminate the polarization bit error rate caused by wavelength interval.The performance of double-reference-pulse polarization compensation scheme is more excellent and the compensation effect is more obvious.However,the multi-reference-pulse scheme has more requirements for laboratory equipment.It is also found that the smaller the wavelength interval is,the smaller the deviation angle of the signal pulse is,and the lower the corresponding polarization error rate is.
