Abstract

A phase compensation technique in the fiber optical quadrature passive demodulation scheme is presented. The phase error between the two interferometric signals is calculated first, and a new signal is generated which has an accurate phase difference of 90° with respect to another one. The experimental results show that the distortion in the demodulated signal is removed and the input signal is correctly recovered. The technique is successfully used in fiber optical interferometric sensors.
