AB  - The out-of-plane optical properties of a combined one-two-dimensional comb-type photonic structure based on macroporous silicon under illumination with polarized normally incident light have been experimentally investigated. Technologically simple quasi-periodic structure with parallel air grooves in the form of mutually overlapping macropores (i.e., one-dimensional air/Si type structure) together with macropores arbitrarily distributed over the crystal surface (two-dimensional air/Si structure) was studied in comparison with the calculated one-dimensional periodic metal lattice on silicon. It is shown that this combined air/Si photonic structure has significant polarization selectivity and can serve as a basis for developing the full-function out-of-plane thermal photodetector on macroporous silicon.
