Abstract:
Three kinds of fiber W-polarizer Panda are described: with lengths 200 m, 1 m, and 50 mm. In the first two cases dichroism is higher than 30 dB, in the third case it is higher than 15 dB. The feature of 50-mm polarizer is the scattering layer in quartz cladding. In each case a most probable physical dichroism mechanisms are described.
