A coarse wavelength division multiplexer is designed on a silicon-on-insulator waveguide using the Mach-Zehnder interferometers with novel multimode interface-periodically segmented waveguide couplers and segmented waveguide arms. It is viable for metro and access applications, since it can be inexpensive and provide easy fabrication, compact size, and good output performance. As a design example, the channel spacing of the demultiplexer is chosen to be 24.5 nm for applications to the 10-Gigabit Ethernet. The simulation results show that the wide-passband demultiplexer can have insertion loss less than 2.3 dB and crosstalk better than 18 dB.
一种粗波分复用器是在绝缘体上硅波导上设计的，它采用了马赫-曾德尔干涉仪，带有新型多模接口——周期性分段波导耦合器和分段波导臂。它适用于城域网和接入应用，因为它成本低廉，易于制造，尺寸紧凑且输出性能良好。作为一个设计示例，解复用器的信道间距被选为24.5纳米，用于10吉比特以太网应用。仿真结果表明，该宽带解复用器的插入损耗可小于2.3分贝，串扰优于18分贝。
