We propose a single-particle Mach-Zehnder interferometer experiment in which the path length of one arm can change before each passage of a particle through the interferometer. We demonstrate that this experiment can be used to determine to which extent quantum theory provides a description of the observed detection events that goes beyond statistical averages or to refute a corpuscular model (...

We demonstrate a two-grating free electron Mach-Zehnder interferometer constructed in transmission microscope. A symmetric binary phase grating and condenser lens system form two spatially separated, focused probes at the sample which can be scanned while maintaining alignment. The paths interfere second grating, creating constructive or destructive interference output beams. This has many nota...

We have demonstrated both rise and fall times below 1 s with 10%–90% modulation in a silicon-on-insulator thermooptical Mach–Zehnder switch. The switch is based on 9m-thick and 10m-wide single-mode rib waveguides. Very fast switching was achieved by using a differential control method. The switch was driven with a digital signal processor accompanied by simple electronic circuitry.
