Single-Mode Propagation in Optical Waveguides and Fibres: A Critical Review of its Treatment in Physics Textbooks
Ruddock, Ivan S.
European Journal of Physics, v30 n2 p303-309 Mar 2009
The derivation and description of the modes in optical waveguides and fibres are reviewed. The version frequently found in undergraduate textbooks is shown to be incorrect and misleading due to the assumption of an axial ray of light corresponding to the lowest order mode. It is pointed out that even the lowest order must still be represented in an elementary treatment by a ray reflecting between opposite core and cladding boundaries. (Contains 7 figures.)
