The National Science Foundation (NSF) Engineering program (CFDA 47.041) has awarded a $450,000 Project Grant to the University of New Mexico (UNM) to develop a generic sensor with enhanced resolution and sensitivity for measuring magnetic field gradients. The 3-year grant, starting on Sep 1, 2024, will fund research on a novel sensing approach that uses dual-propagating frequency combs to directly detect phase rather than signal amplitude. This work aims to miniaturize the sensor setup using on-chip waveguide resonators to improve sensitivity, while also exploring quantum mechanical squeezing techniques to further enhance the signal-to-noise ratio. As an example application, the project will demonstrate the sensor's capabilities in chip-based gradient magnetometry, with potential use cases in areas like medical imaging, navigation, and manufacturing.
