报道了一种采用级联阵列波导光栅和集成移相器的可调谐色散补偿器。它是反射电路，但不需要环行器。成功地将色散控制在+142 ~+1148ps/nm。在使用43 Gbps CSRZ-DQPSK调制的传输实验中，经过色散补偿后确认了无差错传输。
A tunable optical dispersion compensator that uses cascaded arrayed-waveguide gratings and an integrated phase shifter is reported. It is a catoptric circuit but does not require a circulator. The dispersion is successfully controlled from +142 to +1148 ps/nm. Error-free transmission is confirmed after dispersion compensation in a transmission experiment using 43 Gbps CSRZ-DQPSK modulation.
