Paper Abstract

The effects of imperfection in fabrication process on the focusing property of photonic quasicrystal (PQC) slab are investigated. Two kinds of imperfections, in which the radii and the positions of all cylinders in quasicrystal slab independently varied at random, are considered. The results show that the randomness adversely affects on the focusing performance of the quasicrystal lens. And the TE mode is more influenced by disorders than the TM mode. The tolerance of focusing function to radius disorder is smaller than to positional disorder. Our results will contribute to the design of PQC-based focusing devices.
