Квазінаправлені та фотонні моди в двовимірних структурах макропористого кремнію з нанопокриттями SiO 2

W e investigated the IR light absorption oscillations in  2 D macroporous silicon structures with SiO 2  nanocoatings 70–800 nm thick. The Wannier–Stark electro-optical effect due to the strong electric field on Si–SiO 2  interface and an additional electric field of quasi-guided optical modes were analyzed. The photonic modes and band gaps were also considered as peculiarities in absorbance spectra of macroporous silicon structures with a thick SiO 2  nanocoating.
