摘要

We describe single crystalline silicon (c-Si) perfect absorbers (PAs) in visible and near-infrared region based on degenerate critical coupling. We show that not only dipoles, but also quadrupoles play an important role to realize PAs with higher Q-factor. In addition, we demonstrate switchable PAs by hybrid Si meta-atoms with metal-insulator transition materials of VO 2 .
