Omni-directional reflection (ODR) property of one-dimensional photonic crystal (PC) structures consisting of alternate layers of Germanium (Ge), and zinc sulfide (ZnS) has been investigated. The existence of total Omnidirectional reflection band gap in 1D-PC is predicted theoretically. Reflectivity of one dimensional periodic structure for TE and TM-modes at deferent angles of incidence has been calculated by using Transfer Matrix Method (TMM). It is found that the mirror designed with these materials has a ODR range which covers the window of 1550 nm used in optical communications.
