Construction of a Calcium Matter-Wave Interferometer
… the construction of a calcium matter-wave interferometer. The interferometer is based on a Ramsey-Borde scheme, and uses a thermal beam of atoms excited by an optical-frequency transition in calcium. In our experiment four pi/2 pulses of light are delivered to the atoms, which split and …

Measuring atomic properties with an atom interferometer
… which measure atomic properties using an atom interferometer. The interferometer splits the sodium de Broglie wave into two paths, one of which travels through an interaction region. The paths are recombined, and the interference pattern exhibits a phase shift depending on the strength of the …

Temperature insensitive fiber optic interferometer and applications
… a relatively temperature insensitive Michelson interferometer is presented. The modification was accomplished by cleaving the coupler after the minimum taper region and polishing, perpendicular to the endface, to a point just short of the interaction region. This allows one of the two fiber …

Novel Method for Mach-Zehnder Interferometer Phase Stabilization
The Mach-Zehnder Interferometer (MZI) is a device used across many areas of research including quantum computing, optical communication, sensing, and imaging. The proper function of an MZI depends upon the stabilization of the relative phase between its arms as thermal gradients and vibrations can …

Updating and Automating the Virginia Tech Single-Plate Interferometer
The single-plate interferometer is a powerful flow visualization and aerodynamic measurement tool. It can provide full-field data for the density distribution in a non-intrusive manner, and it can be used for highly unsteady flows. While the device itself represents a large decrease in complexity …
