We showed this fact using the volume equivalent current method. The procedure is then applied to a helically bent fiber, and it is shown that the radiation from the helical fiber is also independent of the polarization as long as the fiber is weakly guiding.viii, 42 leaves, illustrationsEnglishinfo:eu-repo/semantics/openAccessTK7871.65 .T169 1990Optical fibers.Fiber optics.Integrated optics.Optoelectronic devices.Optical wave guides.Polarization (Electricity).Thesis
