Cylindrical waveguide modes

WebA lot of propagation modes in planar and cylindrical negative dielectric waveguides have been classified from the point of view of nanophotonics. Physical meanings of the formation of nano-sized optical beam have been discussed by wavenumber surface. Applications to nano-optical devices and excitations have been discussed. WebConsider the cylindrical dielectric waveguide shown in Fig. 4-1, with a solid cylindrical core of refractive index n 1 surrounded by a concentric cladding shell of refractive index n 2. The medium outside the fiber will be taken to have index n 0. A ray of light that enters the fiber end at an angle from the fiber axis will be refracted upon entering, striking the core …
