Electromagnetic wave propagation in optical waveguides.
MetadataShow full item record
This thesis is a theoretical investigation of the propagation characteristics of electromagnetic waves in mono—mode optical fibre waveguides. There are four major aspects in the present study. The basic properties of surface wave modes on a mono-mode optical waveguide with a finite cladding boundary is first analysed with special references to the core and the cladding mode approximations. The next main field of interest is the excitation of the surface waves on the optical waveguide. The conclusions are essential to the consideration for efficient coupling of light energy from a solid state laser into the dominant mode of the fibre. The effects of scattering on the waveguide transmission is then studied. Finally, the propagation characteristics of radially inhomogeneous optical fibres are examined.
