摘要

The transfer matrix method is employed to theoretically investigate the near-infrared (NIR) narrow filter properties in a one-dimensional defective symmetric photonic crystal with a superconductor photonic quantum-well defect (PQW). The study investigates how the wavelength of the defect mode is affected by the stack number of the PQW defect structure, the thicknesses of PQW layers, the polarization, and the angle of incidence as well as the operating temperature. The results also show that the period of the PQW defect structure and the number of defect modes are independent of one another. This result differs from that of studies conducted on a common dielectric or metamaterial defect. It is noted that with an increase in the number of the defect period, the thickness of the superconductor layer, and the angle of incidence, the defect mode shows a blue-shift for both wave polarizations. On the other hand, an opposite trend is observed as the thickness of the air layer and the operating temperature increase. The results also reveal that new tunable narrow filters and optical communication devices can be achieved at NIR region in this proposed structure. (C) 2016 Optical Society of America
