摘要
为了解决相干偏振合成中输入光功率之比和相位差对合成效率影响的问题,本文在分别基于相位控制和基于偏振控制的相干偏振合成方法的基础上,结合两种方法的优点,提出了一种基于相位-偏振组合控制的相干偏振合成设计方法,并通过四路相干偏振合成对其可行性进行了验证。研究结果表明:在闭环的情况下,整个系统的组合效率达到97.61%。该设计方法有效解决了空间激光通信系统中将多路激光耦合至一根光纤中时效率低的问题。
In order to solve the problem of influence of ratio of input optical power and phase difference on the synthesis efficiency in coherent polarization synthesis,based on the phase-controlled and polarization controlled coherent polarization synthesis methods,this paper proposed a coherent polarization synthesis design method based on phase-polarization combination control,which combined with the advantages of the two methods.Then its feasibility was verified by four-way coherent polarization synthesis.And the results showed that,in the case of closed loop,the combined efficiency of the whole system reached 97.61%.The design method effectively solved the problem of low efficiency when coupling multiple lasers into one fiber in space laser communication system.
