Article Abstract

We have developed an amplitude-division type Mach-Zehnder electron interferometer (MZ-EI). The developed MZ-EI is composed of single crystals corresponding to amplitude-division beam splitters, lenses corresponding to mirrors and an objective aperture. The spacings and azimuth angles of interference fringes can be controlled by single crystal materials and their orientations and by diffraction spots selected by the objective aperture. We built the MZ-EI on a 1.2-MV field-emission transmission electron microscope and tested its performance. Results showed that interference fringes were created for various spacings and azimuth angles, which demonstrates the practicability of the MZ-EI as an amplitude-division type electron interferometer.

Experimental observations of flux periodicity ϕ/2, where ϕ = h/e, for interference of the outermost edge mode in the integer quantum Hall regime have been attributed to an exotic electron pairing mechanism. We present measurements of an AlGaAs/GaAs Fabry-Pérot interferometer operated in the integer quantum Hall regime for filling factors 1 ≤ ν ≤ 3 that has been designed to simultaneously express measurable bulk-edge and edge-edge couplings. At integer fillings ν = 2 and ν = 3, we observe interference with flux periodicity ϕ/2 for the outermost edge mode.

The carrier-envelope phase () of few-cycle light pulses is of crucial importance for strong-field light-matter interaction on subcycle time scales. Standard -2 interferometry rapidly records beat notes defined by the carrier-envelope offset frequency (), but measuring at a high bandwidth is more involved. Here, we introduce -2 polarization interferometry, which unambiguously measures over a range of 2π at the detection speed of the implemented photodiodes.

The tunneling of a particle through a barrier is one of the most fundamental and ubiquitous quantum processes. The rapid progress in strong-field physics enables us to resolve the laser-induced tunneling ionization from atoms and molecules at a more precise level. Here we employ a temporal double-slit interferometer to probe the electron wave packet generated from the strong-field-induced tunneling of a molecule.

A novel fiber-optic ammonia Mach-Zehnder interferometer (MZI) with an asymmetric-sensing structure was developed and experimentally validated. The sensor was fabricated through successive fusion splicing of single-mode fiber (SMF), coreless fiber (NCF), SMF, thin-core fiber (TCF), and SMF, thereby forming an SMF-NCF-SMF-TCF-SMF interferometric structure. Experimental and simulation results demonstrated that the sensor exhibited a linear response within the refractive index range of 1.

Optically generated microwaves exhibit unprecedented low noise, benefiting applications such as communications, radar, instrumentation, and metrology. To date, the purest microwave signals are produced using optical frequency division with femtosecond mode-locked lasers. However, their typical repetition rates of hundreds of MHz require multiplication methods to reach the microwave domain.
