报道了一种格形可调谐色散补偿器，通过增加交织滤波器，可操作通道数增加了一倍。在该方案中，交织信号被引入到格形补偿器的两个不同输入，并且每半个自由光谱范围被提供相同的色散补偿值。因此，这种配置可以激活不可操作的通道，占现有的网格形式的补偿器的总带宽的近一半。建议的补偿器制作单片集成与硅波导技术的所有组件。在信道周期为50 GHz的40 GHz带宽上获得了−321至299 ps/nm的色散补偿值。
A lattice-form tuneable chromatic dispersion compensator whose number of operable channels is doubled by adding an interleave filter is reported. In this scheme, interleaved signals are introduced into two different inputs of the lattice-form compensator, and are provided with the same dispersion compensation value every half free spectral range. Thus, this configuration can activate inoperable channels that account for nearly half of the total bandwidth in existing lattice-form compensators. The proposed compensator was fabricated by monolithically integrating all components with silica-waveguide technology. The dispersion compensation value of −321 to 299 ps/nm was obtained over 40 GHz bandwidth with a channel period of 50 GHz.
