Abstract:In this paper, photonic crystal (PC)-based filters with perfect transmittance and narrow-channels located synchronously in zero dispersion (1300 nm) and low-loss (1550 nm) optical fiber communication windows have been introduced. The results demonstrate the potential of 1D photonic crystals for designing of PC-based optical filters with capability of simultaneous filtration of the second and third optical fiber windows even in the presence of oblique incidence angles of light and for both TE- and TM-waves.
Keywords:Optical filter  Photonic crystal  Fiber optics communications  Zero dispersion window  Low-loss window
