Abstract

In the optical fiber communication system, optic passive components such as the optical coupler and acousto-optic modulator have polarization depending on loss (PDL) and polarization depending on gain (PDG). The polarizer can change the light of polarization to unpolarized light, so the apparatus and system dependence of polarization could be reduce. Base on the principle of the Lyot depolarizer, we verified the physics process of Lyot depolarizer and depolarize with improvement by matrix optics and theory of polarizer. Mathematics calculation with computer is used, and this paper provides the curves between residual polarization and crystal wedge. Different polarized states of incident light are obtained. Meanwhile, the results of model are analyzed. The error in produce processing is considered and calculated first time, which is influence the depolarization performance of depolarize. Based on simulate calculate and results, the configure parameters and tolerance design method of an improved Lyot depolarize are also establish.
