Abstract
The band characteristics and the phase shift of electromagnetic waves in one-dimensional Fibonacci photonic structures composed of nano-scale fullerene and semiconductor layers are investigated theoretically in detail for both TE and TM polarizations and for different incident angles. We adopt the transmission matrix method to analyze the transmission properties of supposed sub-wavelength structure. We observe that within the stop band, the reflection phase difference changes smoothly and increases with the increasing of the incident angle. Furthermore, the phase shift decreases with the incident angle increasing for TE mode, and increases with the incident angle increasing for TM mode. Especially, at both the edges of the gap, the reflection phase difference keeps zero in spite of the change of incident angle. Based on our results, the supposed structure provides a convenient way to design very compact phase controllers such as phase retarders.
