本文报道了一种波导型色散补偿器，它由一对阵列波导光栅和一个由100条固定延迟线组成的阵列组成。补偿器采用相对折射率差为2.3%的二氧化硅波导制作。我们通过延迟线将第一个阵列波导光栅输出连接到第二个阵列波导光栅输入。在第一阵列波导光栅处的每个解复用波长分量经历分配的色散补偿延迟，并在第二阵列波导光栅处再次复用。该补偿器可对10个间距为2.0 nm的通道进行色散补偿。得到的色散补偿值和带宽分别约为-53 ps/nm和1.6 nm。该补偿器适用于高速调强信号的色散补偿，包括开关键控信号和脉冲调幅信号。
We report on a waveguide-type chromatic dispersion compensator comprising a pair of arrayed-waveguide gratings and an array of 100 fixed delay lines. The compensator was fabricated with a silica waveguide with the relative index difference of 2.3%. We connected the first arrayed-waveguide grating output to the second arrayed-waveguide grating input through the delay lines. Each demultiplexed wavelength component at the first arrayed-waveguide grating experiences assigned delay for the dispersion compensation and is again multiplexed at the second arrayed-waveguide grating. The compensator can trim the dispersion of ten channels with spacing of 2.0 nm. The obtained dispersion compensation value and bandwidth at each channel were about -53 ps/nm and 1.6 nm, respectively. The compensator is helpful to the dispersion compensation for high-speed intensity-modulated signals including on-off keying and pulse amplitude modulation signals.
