我们基于磁性半导体GaMnAs数值研究一种穿孔全介质超表面。在Anapole态附近,该结构兼具高透射率与中等磁光强度效应:与光滑薄膜相比,绝对透射调制增强约5倍,超表面透射率达81%。该增强与磁光活性材料中的强场局域化,以及Anapole regime中电偶极辐射通道的抑制相关。
英文摘要
We numerically study a perforated all-dielectric metasurface based on the magnetic semiconductor GaMnAs. Near the anapole state, the structure combines high transmittance with a moderate magneto-optical intensity effect. The absolute transmission modulation is enhanced by about a factor of five compared with a smooth film, while the metasurface transmittance reaches 81%. The enhancement is associated with strong field localization in the magneto-optically active material and suppression of the electric-dipole radiation channel in the anapole regime.
