This paper discusses the possibility of obtaining one-dimensional photonic crystals based on a system of periodically etched channels in Si <110>. The characteristic matrix method is used to calculate their reflection spectra, which display wide secondary maxima along with the fundamental photon zone. Structures have been fabricated with a period of 4Ã¢Â€Â“16 um, and their reflection spectra have been studied. It is shown that the experimental spectra coincide with the calculated values in the measurement region of Lambda= 2Ã¢Â€Â“16 um.
