摘要
随着轨道角动量(OAM)光通信技术的研究不断深入,OAM路由器件在提升通信系统的灵活性和实用性方面扮演着重要的角色,近些年,具有特定功能的OAM路由器件的研究得到了飞速发展。基于此,对近些年OAM路由器件的研究成果进行了概述,对其中可实现信道切换、多播、滤波、添加/提取、跳变和模式划分6类OAM路由器件的原理、研究方法及优缺点进行了讨论与总结,同时对OAM路由器件未来的发展趋势进行了展望。
With the development of orbital angular momentum(OAM)based optical communication technology,OAM router played an important role in improving the flexibility and practicability of OAM communication system.In recent years,the research on multifunctional OAM router had also been developed rapidly.Based on this,the research results on the OAM router had been summarized and reviewed,in which the principles,research methods,advantages and disadvantages of six types of OAM router,with the functions of switching,multicast,filtering,adding/extraction,and jumping and mode dividing respectively,had been discussed and summarized in details.Meanwhile,the future developing trend of the OAM router has also been prospected and discussed in the end.
