Abstract
A photonic-crystal electromagnetic-wave device includes a photonic crystal structure having a periodically changed optical property at least in one direction. The photonic crystal structure includes electromagnetic-wave absorptive portions periodically arranged, each of the absorptive portions having an extinction coefficient larger than that of the other portions of the photonic crystal structure.
