Nanosecond photonic switch architectures demonstrated in an all-digital monolithic platform

We present an all-digital, fully programmable, nanosecond-scale photonic switch platform, monolithically integrating electronics for actuation, tuning, and power-monitoring alongside switching elements, resulting in a scalable, packag-eable solution for high-radix photonic switch fabrics. In this platform, we achieve record loss and extinction performances utilizing a 2 × 2 Mach–Zehnder switch (MZS) with 0.8 dB of loss and 28 dB extinction and a 2 × 2 nested MZS with 1.3 dB of loss and 38 dB extinction.
