Explain how light propagates at a given wavelength with a certain phase velocity that depends on the refractive indices of the core and the cladding, as well as on the diameter of the core.
Description This is for a research paper on waveguide modes. (IEEE format). In particular, for “single mode” fiber. Basically need to describe the phase matching condition (peak wavelength = 2 * Effective index * Grating period). This equation needs to be explained/derived/described. Need to explain how light propagates at a given wavelength with a certain […]
