Interferential polychromatic filters based on the quasi-periodic one-dimensional generalized multilayer Thue-Morse structures

In this paper, a new,type of optical filter using photonic band gap materials has been proposed. The optical filter was obtained by a combination of periodic H(LH)(J) and generalized Thue-Morse (GTM) quasi-periodic one-dimensional multilayer. We show that the whole structure H(LH)(J)[TM](P)H(LH)(J), where P is the repetition number of the GTM stack, has an interesting application as a polychromatic filter. However, the effect of the repetition number for producing all improved polychromatic filter is presented. So, switches like (on-on-off-off-on-on- ... ) have been found.
