摘要： Light incident on an input optical fiber is separated into p-polarized light and s-polarized light by a birefringent crystal. A voltage to be applied to a liquid crystal element having electrodes associated with the ray axes of the polarized light waves is controlled in order to convert the p-polarized light into s-polarized so that both the polarized light waves will be s-polarized light. Otherwise, the s-polarized light is converted into p-polarized light so that both the polarized light waves will be p-polarized light. A polarized-wave separation film located behind the liquid crystal element transmits p-polarized light and reflects s-polarized light. When both the polarized light waves propagated through the liquid crystal element are s-polarized light, the light reflected from the polarized-wave separation film is reflected from a total-reflection film, and reflected again from the polarized-wave separation film. The resultant light falls on the birefringent crystal again via the liquid crystal element, and is restored to non-polarized light by the birefringent crystal. The non-polarized light then falls on a first output optical fiber. In contrast, when both the polarized light waves propagated through the liquid crystal element are p-polarized light, the p-polarized light is transmitted by the polarized-wave separation film, and then restored to non-polarized light after falling on the birefringent crystal via another liquid crystal element. The resultant light then falls on a second output optical fiber.
摘要翻译： 入射到输入光纤的光被双折射晶体分离成p偏振光和s偏振光。 控制施加到具有与偏振光的射线轴相关联的电极的液晶元件的电压，以便将p偏振光转换成s偏振光，使得两个偏振光将是s偏振光 。 否则，s偏振光被转换成p偏振光，使得两个偏振光都将是p偏振光。 位于液晶元件后面的偏振波分离膜透过p偏振光并反射s偏振光。 当通过液晶元件传播的两个偏振光都是s偏振光时，从偏振波分离膜反射的光从全反射膜反射，并从偏振波分离膜再次反射。 所得到的光通过液晶元件再次落在双折射晶体上，并通过双折射晶体恢复为非偏振光。 然后，非偏振光落在第一输出光纤上。 相反，当通过液晶元件传播的两个偏振光都是p偏振光时，p偏振光被偏振波分离膜透射，然后在落在双折射晶体上后恢复为非偏振光 通过另一液晶元件。 所得到的光然后落在第二输出光纤上。
