Abstract
We firstly present a concept of a self-calibration of the classical and quantum parameters' measurement using a fiber optic system. The measurement of the change in phase of the optimum entangled states' visibility is performed in terms of a walk-off length, i.e. birefringence. The applied physical parameters on the sensing fiber can be simultaneously measured and the self-calibration respecting the birefringence performed. The scheme of the entangled photons generation in fiber optic is reviewed and the walk-off on the polarization entangled states presented. The potential of self-calibration and simultaneous measurement using an interferometric sensing technique and fiber grating sensor are proposed and discussed. The walk-off on the entangled states in the thermal-controlled environment is presented and discussed. © 2009 Elsevier GmbH. All rights reserved.
