摘要
提出了一种基于微环谐振器的光分组头串并转换方法。采用环层叠和多级级联结构设计微环谐振器，在正弦控制电压的作用下产生一个较窄的开关窗口，实现光分组头的串并转换。采用时域有限差分法分析了系统的性能。研究结果显示开关窗口宽度、消光比和插入损耗分别优于14．9ps、36．4dB和1dB，可实现160～40Gbit／s和40～10Gbit／s的光分组头串并转换。
An optical header serial-to-parallel conversion technology using microring resonators is reported. The microring resonator is predicted to fabricate by using Pockler electro-optic materials. The microring resonators possess a multistage-cascaded structure to satisfy the requirement to generate a switching window using sine wave electrical control signal. Several resonators are arranged in parallel to accomplish serial-to-parallel conversion. The system performances are researched using finite difference time domain method. Results show that the width, extinction ratio and the insertion loss of the switching window are better than 14.9 ps,36.4 dB and 1 dB, respectively. It can stratify the requirements of 160-40 Gbit/s and 40-10 Gbit/s optical header serial-to-parallel conversion.
