In order to improve the transmission and durability of infrared optical materials, the antireflection characteristics of two dimensional sub-wavelength structures on infrared optical materials were investigated. The results of numerical modeling showed two dimensional sub-wavelength structures can improve the transmission of infrared optical materials over a broad band, especially pyramid structures. Then two dimensional sub-wavelength structures on Zinc sulfide were fabricated with contacting ultraviolet lithography and reactive ion etching, A substantial antireflection effect was obtained over the wavelength band 8~12 μm. To improve the environmental durability of the antireflective sub-wavelength structures, Germanium carbide film was deposited on the two dimensional sub-wavelength structures by reactive RF magnetron sputtering.

Sub-wavelength artificial photonic structures can be introduced to tailor and modulate the spectrum of materials, thus expanding the optical applications of these materials. On the basis of SiO2/Cu/ITO arrays, a hybrid coupled resonance (HCR) mechanism, including the epsilon-near-zero (ENZ) mode of ITO, local surface plasmon resonance (LSPR) mode and the microstructural gap resonance (GR) mode, was proposed and researched by systematically regulating the array period and layer thickness. The optical absorptions of the arrays were simulated under different conditions by the finite-difference time-domain (FDTD) method. ITO films were prepared and characterized to verify the existence of ENZ mode and Mie theory was used to describe the LSPR mode. The cross-sectional electric field distribution was analyzed while SiO2/Cu/ITO multilayers were also fabricated, of which absorption was measured and calculated by Macleod simulation to prove the existence of GR and LSPR mode. Finally, the broad-band tailoring of optical absorption peaks from 673 nm to 1873 nm with the intensities from 1.8 to 0.41 was realized, which expands the applications of ITO-based plasmonic metamaterials in the near infrared (NIR) region.
