Vibration induced phase noise in Mach-Zehnder atom interferometers

Demonstration of displacement- and frequency-noise-free laser interferometry using bidirectional Mach-Zehnder interferometers.

We have demonstrated displacement- and frequency-noise-free laser interferometry (DFI) by partially implementing a recently proposed optical configuration using bidirectional Mach-Zehnder interferometers (MZIs). This partial implementation, the minimum necessary to be called DFI, has confirmed the essential feature of DFI: the combination of two MZI signals can be carried out in a way that canc...

Interactions in electronic Mach-Zehnder interferometers with copropagating edge channels.

We study Coulomb interactions in the finite bias response of Mach-Zehnder interferometers, which exploit copropagating edge states in the integer quantum Hall effect. Here, interactions are particularly important since the coherent coupling of edge channels is due to a resonant mechanism that is spoiled by inelastic processes. We find that interactions yield a saturation, as a function of bias ...

Event - based simulation of single - photon beam splitters and Mach - Zehnder interferometers ( ∗ )

– We demonstrate that networks of locally connected processing units with a primitive learning capability exhibit behavior that is usually only attributed to quantum systems. We describe networks that simulate single-photon beam-splitter and Mach-Zehnder interferom-eter experiments on a causal, event-by-event basis and demonstrate that the simulation results are in excellent agreement with quan...

Integrated Lithium Niobate Mach-Zehnder Interferometers for Advanced Modulation Formats

We present recent progress of high-speed Mach-Zehnder modulator technologies for advanced modulation formats. Multi-level quadrature amplitude modulation signal can be synthesized by using parallel Mach-Zehnder modulators. We can generate complicated multi-level optical signals from binary data streams, where binary modulated signals are vectorially summed in optical circuits. Frequency respons...
