Light Pulse Atom Interferometry (LPAI) utilizes stimulated Raman transitions to split, redirect, and recombine atomic wavepackets along a single dimension. We investigate the implementation of LPAI in optical atomic guides that constrain the transverse motion, specifically, the evanescent mode surrounding a tapered optical fiber (TOF). TOFs have the potential to increase the detection fidelity of atomic states while simultaneously reducing the power required to drive LPAI pulse sequences. In addition, the micron-scale confinement in TOF guides can be leveraged to probe fundamental physics of near-surface dynamics such as inverse square law violations and Casimir-Polder force measurements.
