Abstract :
An algorithm which allows the analysis of optical periodic structures with a very large number of periods with minimum numerical problems is presented, For this purpose the stable impedance transfer is combined with Floquet´s theorem. Numerical results for a Bragg grating with up to 20000 periods are presented featuring the very moderate numerical effort
