    In this paper, the properties of the defect mode in the photonic band gap of
    one-dimensional ternary photonic crystals containing high temperature superconductor
    layer (SPCs) have been theoretically investigated. We considered the quasi-periodic
    layered structures by choosing two order of ternary Thue-Morse structures with mirror
    symmetry. We investigated the transmission spectra of these structures by using the
    transfer matrix method and two-fluid model. It is found that the location of defect mode
    and the range of photonic band gap can be changed by the incident angle. So that, the
    defect mode blue-shifted and disappeared by increasing the incidence angle. We
    observed an omnidirectional photonic band gap for the TE polarization that its range is
    from 456nm to 520nm. Also, the defect mode can be tuned by the temperature. As a
    result, the width of defect mode can be decreased by increasing the temperature,
    especially in the vicinity of the critical temperature of superconductor layer. This kind
    of SPCs has potential applications in filters, sensors and so on. Manuscript profile
