Paper Abstract

The gain coupled gratings are analyzed by the extension of a well-known coupled mode theory, first developed by Streifer et al. in 1977. We present a new matrix method that takes into account the polarization nature of the non-dominant modes, that has been ignored in the previous theories. Our method can analyze any grating irrespective of its shape, its order and its type. It is based on slicing the grating layer such that in each layer, the equivalent waveguide refractive index and excitation can be considered as constants. We obtain different coupled wave equations, as we applied this method to pure gain coupled DFB lasers. It is worth noting that our theory is presented in the under threshold regime.
