Enhanced atom interferometer readout through the application of phase shear
Alex Sugarbaker, Susannah M. Dickerson, Jason M. Hogan +2
We present a method for determining the phase and contrast of a single shot of an atom interferometer. The application of a phase shear across the atom ensemble yields a spatially…
Multi-axis inertial sensing with long-time point source atom interferometry
Susannah M. Dickerson, Jason M. Hogan, Alex Sugarbaker +2
We show that light-pulse atom interferometry with atomic point sources and spatially resolved detection enables multi-axis (two rotation, one acceleration) precision inertial sensi…
A Precision Angle Sensor using an Optical Lever inside a Sagnac Interferometer
J. M. Hogan, J. Hammer, S. -w. Chiow +5
We built an ultra low noise angle sensor by combining a folded optical lever and a Sagnac interferometer. The instrument has a measured noise floor of 1.3 prad / Hz^(1/2) at 2.4 kH…
An Atomic Gravitational Wave Interferometric Sensor in Low Earth Orbit (AGIS-LEO)
Jason M. Hogan, David M. S. Johnson, Susannah Dickerson +11
We propose an atom interferometer gravitational wave detector in low Earth orbit (AGIS-LEO). Gravitational waves can be observed by comparing a pair of atom interferometers separat…
Optical Lattices as Waveguides and Beam Splitters for Atom Interferometry: An Analytical Treatment and Proposal of Applications
Tim Kovachy, Jason M. Hogan, David M. S. Johnson +1
We provide an analytical description of the dynamics of an atom in an optical lattice using the method of perturbative adiabatic expansion. A precise understanding of the lattice-a…
Broadband Optical Serrodyne Frequency Shifting
D. M. S. Johnson, J. M. Hogan, S. -w. Chiow +1
We demonstrate serrodyne frequency shifting of light from 200 MHz to 1.2 GHz with an efficiency of better than 60 percent. The frequency shift is imparted by an electro-optic phase…
