【摘要】 本文用光学方法,即微分琼斯矩阵研究单模光纤的极化特性。首先推导了单模光纤的微分琼斯矩阵方程,并引入微分琼斯矩阵的表象理论。将其应用于较复杂的多重微扰单模光纤,使双折射及极化公式具有极其简单的形式和明确的物理意义。最后给出了扭转椭圆芯光纤的极化公式.更多还原

【Abstract】 Polarization properties of single-mode fibers have been investigated by using the differential Jones-matrices. The differential Jones vector equation is derived, then the representation theory of differential Jones-matrix is introduced. Applying then to complex multiply perturbed single-mode fibers, the expressions of birefringence and evolution of polarization are found to be very simple and quite intuitive. The formula for polarization evolution of twisted fibers with an elliptical core is given.更多还原
