Abstract
In this paper, a novel polarization analyzer for measuring the state of polarization of light is proposed. The analyzer consists of a TE-TM mode splitter, a passive TE-TM mode converter, and three polarizers. Comparing with the previously reported methods, without using mechanically movable and actively modulated components for polarization control, the time response of measurement is less limited and the signal process for the determination of polarization parameters is easier. Where, the polarization parameters are obtained via three received optical signals based on the proposed methods. Moreover, the concept can be realized by waveguide or fiber devices, which are more compact. The dependence of measurement performance on the characteristics of composed elements is theoretically investigated and the results show that the measurement resolutions are determined mainly by the characterisation of individual elements.
