Near infrared ultra compact phase retarders based on photonic superlattices containing fullerene layers

In this paper, we report the analysis of the electromagnetic wave transmission having a wave length near infrared propagating in Fibonacci quasiperiodic multilayer structures made of fullerene and germanium materials. We observe that within the stop band the reflection phase difference changes smoothly and increases with the increasing of the incident angle. In the center of the gap the reflection phase difference remains almost unchanged in a broad wavelength band. Especially, at both the edges of the gap the reflection phase difference keeps zero in spite of the change of incident angle. Basing on our results, the supposed structure provides a convenient way to design very compact phase controllers such as phase retarders.
