Simultaneous operation of a dual-channel optical filter in zero dispersion and low-loss optical fiber windows based on a special double-cavity photonic crystal

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.
