Fiber-based interferometers are compact, robust and cheap, thus are ubiquitously deployed. However, the optical phase in fiber interferometers is sensitive to ambient perturbation, resulting in compromised phase sensing precision. Therefore, phase control, shifting and stabilization of fiber interferometers is essential.
