Single-Polarization Single-Mode Optical Waveguiding SchemesIn ordinary axially symmetrical optical fibers, the polarization state of the propagated wave is subject to unstable fluctuation when ambient conditions change. In a multimode fiber, such instability usually causes little trouble except for its possible effect on modal noise. However, in a singlemode fiber, the following problems arise .
