Abstract

Mechanisms of the negative and imaginary parts of the permittivity formation in 2D photonic macroporous silicon structures are investigated. Negative part of permittivity in 2D photonic macroporous silicon structures is determined by the polaritonic and surface electromagnetic mode formation. One of mechanisms of the imaginary permittivity formation is the electro-optical effect realized clearly in 2D photonic macroporous silicon structures in the near-IR area (impurity absorption). We investigated the "out-of-plane" optical absorption of 2D photonic macroporous silicon structures taking into account the optical mode formation and the electro-optical effect. The reflected electromagnetic waves at grazing angle of light incidence onto macropore surface change effectively the local surface electric field.
