Optomechanical inertial sensors
Abstract
We present a performance analysis of compact monolithic optomechanical inertial sensors that describes their key fundamental limits and overall acceleration noise floor. Performance simulations for low frequency gravity-sensitive inertial sensors show attainable acceleration noise floors of the order of 10^-11 ms^-2/rtHz. Furthermore, from our performance models, we determine the optimization criteria in our sensor designs, sensitivity, and bandwidth trade space. We conducted characterization measurements of these compact mechanical resonators, demonstrating mQ-products at levels of 250kg, which highlight their exquisite acceleration sensitivity.
