报道了一种混合集成对称马赫-曾德尔（HI-SMZ）全光开关。在<4 ps的开关速度下，它具有>20 dB的动态消光比。在1 ps的控制脉冲下，其上升和下降时间没有延迟。因此，HI-SMZ全光开关能够进行高消光、准方形调制，其速度高达/spl sim/4 ps，对应于超过200 Gbit/s的比特率。
A hybrid integrated symmetric Mach-Zehnder (HI-SMZ) all-optical switch is reported. It has a very high dynamic extinction ratio of >20 dB at a switching speed of <4 ps. No delay was found in its rise and fall times with 1 ps control pulses. Thus, the HI-SMZ all-optical switch is capable of high extinction, quasi-square-like modulation up to a speed of /spl sim/4 ps, corresponding to a bit rate exceeding 200 Gbit/s.
