Abstract

The invention relates to the optoelectronics, in particular to the optical filters, and may be used in the optical systems. The optical filter in the form of photon two-dimensional crystal includes a matrix and cylinders of semiconductor or dielectric material, incorporated into the matrix perpendicular to its base and parallel to each other. The refractive index of the matrix material is smaller than the refractive index of the cylinder material. Novelty consists in that onto the matrix base surface there is deposited a metal mask, the bases of the cylinders being placed in the same plane with it.Claims: 1Fig.: 2
