我们首次报道了单片集成混合扩张2×2模块化光开关的实验演示，该开关使用马赫-曾德尔调制器作为低损耗1×2开关元件和短半导体光放大器来提供额外的消光和增益。一个优秀的40 dB的串扰/消光比记录与数据调制的信噪比高达44 dB的0.1 nm的带宽。开关时间为3 ns。误码率研究表明，子系统的损失极低，小于0.1 dB，研究表明，通过使用这种混合开关构建块，可以实现8×8端口开关，输入功率动态范围为14 dB，子系统的损失小于0.5 dB。
We report the first experimental demonstration of a monolithically integrated hybrid dilated 2×2 modular optical switch using Mach-Zehnder modulators as low-loss 1×2 switching elements and short semiconductor optical amplifiers to provide additional extinction and gain. An excellent 40 dB cross-talk/extinction ratio is recorded with data-modulated signal-to-noise ratios of up to 44 dB in a 0.1 nm bandwidth. A switching time of 3 ns is demonstrated. Bit error rate studies show extremely low subsystem penalties of less than 0.1 dB, and studies indicate that, by using this hybrid switch building block, an 8×8 port switch could be achieved with 14 dB input power dynamic range for subsystem penalties of less than 0.5 dB.
