为了获得高质量无色差的多波长相干艾里光束,提出了一种基于变形镜的多波长艾里光束生成方法,并通过仿真与实验研究了多波长艾里光束的传播特性。实验结果表明,变形镜可以有效消除色差对光束的影响,生成高质量的多波长艾里光束;且传播中主瓣不会发生色差分离和衍射。此外,生成的多波长艾里光束主瓣被不透明障碍物遮挡后,经过一段距离传播后可自行恢复。本研究为多波长艾里光束在多光谱成像和光学微操作等领域中的应用提供了一定的基础。

无源光网络(PON)通常采用二进制非归零码(NRZ)调制技术,该技术存在如下缺点:系统的频谱效率最低,对无源光网络中相邻射频(RF)电视信道产生拉曼串扰影响,以及高速传输时光纤色散代价大。为了克服上述问题,采用了将正交频分复用(OFDM)调制技术应用于PON系统的解决方法。对基于强度调制和雪崩光电二极管(APD)直接检测的10 Gb/s 16位正交幅度调制(16QAM)OFDM-PON系统进行了100 km的下行方向传输实验。实验结果表明,在误码率(BER)水平为1×10-3的条件下,系统接收灵敏度可以达
