Abstract:
An analytical investigation has been presented of Au nano- coated dielectric optical fibers. The propagation constants of different transverse TE and hybrid EH modes are obtained corresponding to varying nano-coating thickness. It has been observed that the Au-layer has its profound effect on the number of propagating modes in the fiber, and the number of sustained modes is much reduced with the increase in Au-layer thickness. For the sake of comparative investigation, the modal behavior of three-layer dielectric fibers is also taken into account together with the Au nano-coated four-layer fiber. It is reported that the Au-layer has the effect of mode proliferation with simultaneous reduction in their propagation constant values.
