提出了一种基于高对比度（33 dB）的载片半导体光放大器的超快电光放大开关。采用多脉冲阶跃注入电流技术，实现了开关时间高达115 ps，过冲小。这些结果与以前的preimpulse阶跃注入电流技术相比，并实现了固有的减少，开关后的增益波动，而不会恶化的开关时间。此外，对控制这种电光开关的脉冲格式进行了数值分析，并与实验结果进行了比较。
An ultrafast electro-optical amplified switch based on chip-on-carrier semiconductor optical amplifier with high optical contrast (33 dB) is presented. Switching times up to 115 ps with small overshoot were achieved by using the multi-impulse step injected current technique. These results are compared with previous preimpulse step injected current technique, and achieve a reduction of the inherent, post switching gain fluctuations without worsening the switching times. In addition, pulse formats for controlling such a kind of electro-optical switches are numerically analyzed and compared with experiments.
