摘要
文章提出了一种基于马赫曾德尔干涉结构的硅基波分复用器。该器件可通过集成的电光移相器实现对器件中各通道传输谱的调节﹐来补偿外界温度变换和工艺误差造成的波长漂移。测试结果表明,热光移相器的效率为3 mW/π,可以实现4个通道的波分复用,通道间隔为3.3nm,隔离度大于30 dB。
This paper presents a silicon wavelength multiplexer based on Mach-Zehnder Interferometer.The device can control the transmission spectrum of each channel by the integrated electro-optical phase shifter to compensate the wavelength drift caused by the external temperature conversion and process error.The measurement results show the efficiency of the phase shifter is 3 mW/π and it can realize four wavelength division multiplexing.The channel spacing is 3.3 nm and the isolation is more than 30 dB.
