Abstract

An infrared wire-grid polarizer consisting of a 400-nm pitch Au grating on a photocuring film with ∼30 μm thickness was fabricated using photoimprinting, thermal evaporation, and peeling off the imprinted film from the substrate in a high humidity environment. This element exhibited a transverse magnetic transmittance greater than 75% in the 4- to 5.5-μm wavelength range because of thin film and an extinction ratio typically greater than 20 dB in the 2.5- to 7.5-μm wavelength range. The maximum extinction ratio of this element exceeded 28 dB at 6.5 μm wavelength. This film polarizer with high TM transmittance can be fabricated at lower costs and simpler fabrication processes compared to conventional infrared polarizers.
