We propose a new concept of birefringence-based sensing using entangled-photon timing-walk-off compensation. Four-wave mixing within a micro-ring resonator is employed, which is introduced by the nonlinear Kerr effect. The two possible entangled photon pairs are randomly formed by using an external polarization control unit. Results obtained have shown that the entangled-photon walk-off state within the ring device can be compensated. This means that the changes in walk-off-state parameters can be measured in response to changes in the applied physical parameters. The experimentally determined relationship between temperature and the entangled-photon walk-off parameter is seen to be in good agreement with the theoretical predictions. The potential of using the proposed system for the development of birefringence-based sensing systems is discussed.
