| 摘 要： | 提出并论证了一种反射型四端口闭环光环行器的设计方案.采用该设计时所有光路端口均在器件同一侧,并可以采取两种光路结构获得光路循环的功能.理论分析了其实现原理以及各个光学参量,实验证实了该方案的有效性.设计结果表明,采用该方案能使光环行器结构更紧凑,减少了装配所需的元件,有利于降低器件成本和装配难度,器件性能与传统直通型双级法拉第旋光片结构的光环行器的性能类似.

| Abstract: | The design and fabrication for a loop optical circulator was proposed,which can take two forms with different optical arrangements.Its working priciple and optical performance are analyzed by theoretical simulation,and the effectiveness was validated by experimental results.Results indicate that the scheme can make device more compact only using one stage of Faraday Rotator(FR).Compared with traditional circulators,the optical performance is similar to a circulator with two stage of FRs.This compact design ... |
