Abstract: A one-dimensional photonic crystal with a variable period has been fabricated from porous anodic alumina. A stepwise increase in the period has ensured the broadening of the photonic bandgap from 50 to 170 nm. It has been shown that the introduction of water, alcohol, or acetone into the pores of the crystal allows one to modify the transmission spectrum and to split the passband. It is shown that the combination of angular incidence of light with pore filling makes it possible to use the fabricated crystal as a broad- and narrowband reusable filter.
