Abstract
Photonic crystals (PCs) and metamaterials are periodic artificial structures with different scales that modulate light–matter interactions. Considering their complementary advantages, the concept of photonic meta-crystals is proposed. In photonic meta-crystals, such as hypercrystals (composed of hyperbolic metamaterials and PCs), the photonic band gap provided by PCs can be blue-shifted with more degrees of freedom, and the weak coupling of hyperbolic metamaterials to the environment can be enhanced. In this review, photonic meta-crystals are introduced sequentially based on the classifications of electromagnetic parameters in metamaterials. Finally, recent advances in photonic meta-crystals are presented in the context of topological semimetals.
