Omni-directional photonic bandgaps (PBG) has been presented in the one-dimensional binary and ternary photonic crystals by using the semiconductor and dielectric materials layers of Si, SiO2 and ZnS in the unit cell. The effect of temperature and angle of incidence on omnidirectional reflection (ODR) spectra of proposed structure for TE and TM polarization has also been studied. The PBG can be tuned by varying the temperature of the semiconductor material Si or by changing the angle of incidence. The ODR range can be increased by introducing the third layer of semiconductor materials in binary Photonic crystals. The existence of total Omni-directional reflection band gap at 1550 nm in 1D binary and ternary photonic crystal is predicted theoretically by using TMM method.
