The modified binary one-dimensional photonic crystal (MB-1DPC), ternary 1DPC (T-1DPC) and heterostructured ternary 1DPC (HT-1DPC) are investigated to achieve the omnidirectional total reflection in the free-space optical communication dual-band range of 810 nm ~ 910 nm and 1550 nm ~ 1610 nm. With material absorption, the reflectivity in the dual-band range for the binary 1DPC (B-1DPC), MB-1DPC, T-1DPC, and HT-1DPC have been studied. The maximum value of reflectivity in each structure that can be achieved in the dual-band range is determined by the TM polarization. The highest reflectivity can reach up to 99.62% for TM mode by employing HT-1DPC multilayers, which is composed of Si, As 2Se3 and SiO2..
