摘要：
The effect of asymmetric on the transmission properties of one-dimensional temary photonic crystal (CmAmBm)n (BmAmCm)n is studied by transfer matrix theory and numerical simulation method. The result shows that when the photonic crystal is a mirror symmetrical structure (CAB)n(BAC)n, the single transmission peak in the band of spectrum becomes fine with increase of cycle number n, but the transmittance and the wavelength position of transmission peak are unchanged. When the symmetry of the photonic crystal is destroyed, the transmittance of single peak is decrease rapidly, but the wavelength position of transmission peak is constant. The transmittance of single peak is decreasing in varying degrees with increase of asymmetry of the thickness of A, B or C medium layer, and the wavelength position of transmission peak is shifting to long wave direction. However, when the asymmetry of the thickness of A, B and C medium layer are increased at the same time, the transmittance of peak isdecreasing and the position of peak is fast blue-shift. The effect mechanism of asymmetry on the transmission properties of One-dimensional temary photonic crystal can provide the theoretical guidance for research and design of optical filter, optical switch and total reflection device. © 2016, Editorial Board of Journal of Infrared and Laser Engineering.
