The process of fabricating photonic crystals comprised of alternately stacked high-and low-index dielectric materials on periodic substrates to form zigzag films is called the autocloning technique. In this study, we have fabricated TiO(2)/SiO(2) two-dimensional polarization filters by using electron beam gun evaporation with ion-beam-assisted deposition. The shape of the zigzag structure is preserved, and the total thickness is 8 mu m. The symmetric structural design can be utilized as an antireflection coating applied to reduce ripples and achieve a 200nm working wavelength range. (C) 2011 Optical Society of America
