• Abstract: A preselection-free fiber-optic weak measurement sensing framework is proposed and experimentally verified in this paper. In view of the limitation that fiber-optic weak measurement require specific preselection, this scheme innovates theoretically and achieves high sensitivity sensing by optimizing the post-selection when single-mode optical fiber is used to generate random polarization state. The experimental results show that the sensing performance is two to three orders of magnitude higher than that of traditional optical fiber sensing technology.

  Weak value amplification technique can provide high sensitivity and precision for optical sensing and metrology. It is more suitable to implement WVA based on optical fiber platform due to the lower cost, smaller scale and higher stability. In our experiment, even the angular misalignment on optical axes at the interface reaches 0.08rad, the sensitivity loss can be maintained less than 3dB.
