摘　　要：Novel optical properties in graded photonic super-crystals can be further explored if new types of graded photonic super-crystals are fabricated.In this paper,we report holographic fabrication of graded photonic super-crystal with eight graded lattice clusters surrounding the central non-gradient lattices through pixel-by-pixel phase engineering in a spatial light modulator.The prospect of applications of octagon graded photonic super-crystal in topological photonics is discussed through photonic band gap engineering and coupled ring resonators.
