Modes of a planar waveguide with Fermi index profile
Wave equations of a planar waveguide with Fermi index profile are studied theoretically. Analytical solutions have been obtained in terms of hypergeometric functions. It has been found that the characteristic equations can be expressed as rapidly converging infinite series of functions of the mode refractive index. Rather accurate results can be obtained by only taking the zeroth-order approximation.
