Design of a Narrow-Band Photonic Crystal Based Omni-Directional Mirror for Optical Fiber
نویسندگان
چکیده
Omni-directional reflection (ODR) property of one-dimensional photonic crystal (PC) structures consisting of alternate layers of Germanium (Ge), and calcium fluoride (CaF2). The existence of total Omni-directional reflection band gap in 1D-PC is predicted theoretically. Reflectivity of one dimensional periodic structure for TE and TM-modes at different 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 1550nm used in optical communications.

متن کاملImprovement of Optical Properties in Hexagonal Index-guiding Photonic Crystal Fiber for Optical Communications
Waveguides with low confinement loss, low chromatic dispersion, and low nonlinear effects are used in optical communication systems. Optical fibers can also be employed in such systems. Besides optical fibers, photonic crystal fibers are also highly suitable transmission media for optical communication systems. In this paper, we introduce two new designs of index-guiding photonic crystal fiber ...
