摘要：

We calculate the second harmonic generation (SHG) from an antiferromagnetic film (AFF) embedded in a one-dimension photonic crystal. The electromagnetic wave localization in the AFF leads to a giant enhancement of the SHG. The numerical results based on three typical structures show that the highest power of SH outputs reaches several hundred times that of a single AFF for the same incident power. The SH outputs depend sensitively on the structural geometry and symmetry, and the best structure and the best layer-thickness matching for it are found. The SHG nonreciprocity is very obvious; i.e., if the direction of incident radiation is reversed, the SH output powers can be changed by several dozens times. Three narrow and obvious SHG bands are found.
