We present a Mach-Zehnder-based optical switch with novel electro-optic shift-and-dump phase shifters that have no residual amplitude modulation. As a result, the switch can have a very high extinction ratio with no overhead in power dissipation and insertion loss compared to standard electro-optic Mach-Zehnder switches. We fabricate the switch in an all-digital silicon photonic platform that monolithically integrates the actuation and control electronics together with the photonics. The switch demonstrates an extinction ratio > 33 dB, insertion loss < 1.2 dB, and nanosecond-scale transients.
