The polarization matrix formalism is employed to analyze the polarization properties of transmitted narrowband light through several optical setups involving active and dissipative structures. It is demonstrated that the degree of polarization of the output light can increase after propagation in a active/dissipative periodic media. Furthermore, the impact of introducing optical elements like polarizers, compensators, and rotators is examined, and their collective effect on the degree of polarization is discussed.

耗散光学系统中的偏振度

偏振矩阵形式用于通过涉及有源和耗散结构的多种光学设置来分析透射窄带光的偏振特性。事实证明，输出光的偏振度在有源/耗散周期性介质中传播后会增加。此外，还研究了引入偏振器、补偿器和旋转器等光学元件的影响，并讨论了它们对偏振度的集体影响。
