Abstract

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]^PH(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 an improved polychromatic filter is presented. So, switches like (on–on–off–off–on–on–…) have been found.
