We demonstrate an elastic multi-wavelength selective switch with up to two wavelength switching capability per crosspoint. We fabricated the switch in a silicon photonics foundry and demonstrated a 17 nm tuning range for ring resonators, with a mean path loss of 2.43 dB. This is a 70% reduction in path loss as compared to previous generations, and we demonstrate a high-speed pulse-amplitude-modulation-4 transmission at 111 Gbps through different paths of the switch.

我们演示了一个弹性的多波长选择开关，每个交叉点最多具有两个波长切换功能。我们在硅光子铸造厂制造了该开关，并展示了环形谐振器的17 nm调谐范围，平均路径损耗为2.43 dB。与前几代产品相比，它的路径损耗降低了70％，并且我们展示了通过开关的不同路径以111 Gbps的速度高速脉冲幅度调制4传输。
