摘要：

We investigate the use of a nonlinear optical interferometer to estimate local gravitational acceleration. We study a Mach-Zehnder interferometer (MZI) in an optical fountain configuration where a Kerr nonlinear medium is placed in the arms of the interferometer. This configuration allows the parameter estimation to exceed the standard Heisenberg limit of a linear interferometer. Compared to previous studies, we argue that this interferometer configuration is better posed and achieves improved precision for similar scale and pump powers. (C) 2022 Optica Publishing Group
