Paper Abstract

We demonstrate that a 2D eight-fold photonic quasi-crystal (PQC) can be produced by a specially designed prism via single-exposure holographic lithography. Compared with traditional eight beams in half space for eight-fold quasi-crystal, we only use 5 beams in ¼ space. From group theory and computer simulation, we have verified the feasibility of the particular configuration and observed the simulated patterns. Experimental results observed under SEM agree well with the expectation, confirming that the specially designed prism can be used to fabricate eight-fold photonic quasi-crystal. This prism-assisted holographic lithography using less exposure beams may benefit mass production of complex quasi-structures.
