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, packageable solution for high-radix photonic switch fabrics. Furthermore by utilizing this platform, we achieve record loss and extinction performances comprising a 2x2 Mach Zehnder switch with 0.8 dB of loss and 28 dB extinction and a 2x2 nested Mach Zehnder switch with 1.3 dB of loss and 38 dB extinction.
