Paper Abstract

We present here a perturbation approach to study the modes of a waveguide with sinusoidal variation of refractive index within or outside the guiding region; the sinusoidal term has been assumed to be the perturbation over the average refractive index profile. The results of the method have been tested by comparing them with numerical results and it has been shown that the perturbation method gives extremely accurate results for large number of oscillation in the guiding region even for a large perturbation. The method should be useful for the analysis of structures with sinusoidal variation of refractive index in the transverse direction, such as in multiple quantum wells.
