研制了一种大偏振分束角的新型空间走离偏振器。该偏振器利用人工各向异性偏振，由周期性层叠的a-Si：H/SiO2薄膜层组成。每层的厚度为67 nm，而层的总数为1440。在λ = 1时，测得的偏振分束角为15.5度。55 μ m，这是现有偏振器的2.7倍。
A new spatial walk-off polarizer with a large polarization-splitting angle is fabricated. The polarizer, which utilizes artificial anisotropic dielectrics, is composed of layers of periodically laminated a-Si:H/SiO2 thin films. The thickness of each layer is 67 nm, while the total number of the layers amounts to 1440. The measured polarization-splitting angle is 15.5-degrees-at lambda = 1. 55 mum, which is 2.7 times larger than that of existing polarizers.
