We present a theoretical analysis of recently demonstrated ultrafast all-optical interferometric switching devices (based on Sagnac and Mach–Zehnder interferometers) that use a large optical nonlinearity in a resonant regime. These devices achieve ∼10-ps switching windows and do not require high-energy optical control pulses. We theoretically analyze and compare one Sagnac and two Mach–Zehnder switching configurations.
