Abstract

Recently, Eberly et al. [1] introduced the polarization coherence theorem (PCT): $P^{2}=V^{2}+D^{2}$ , where the polarization $P$ , visibility $V$ , and distinguishability $D$ are joined. In this work, we study the PCT in birefringent nonlinear single-mode optical fibers by considering circularly polarized input light fluctuating in amplitude. We analyze the behavior of the output PCT as a function of the linear birefringence and average input power. We demonstrate that the output light field undergoes a reduction of $P$ and $V$ but an increase of $D$ when the linear birefringence approaches a critical value defined by the average input power; otherwise, $P$ , $V$ , and $D$ remain unaffected. We also show how the average input power impacts $P$ , $V$ , and $D$ by enhancing the linear birefringence.
