Abstract

Broadband terahertz polarizers based on one-dimensional metal grids on carrying thin-film polymeric substrates of different thicknesses were manufactured by photolithography and investigated with terahertz time-domain spectroscopy (THz-TDS). Polarizers patterned on 4μm polypropylene (PP) showed the best maximum power transmission >98%. Two 4-μm-PP polarizers assembled as a tandem structure exhibited minimum power transmission <1·10-4 in the spectral range of 0.2-2 THz. This corresponded to the extinction ratio >10000:1 which exceeded the dynamic range of THz-TDS. The developed polarizers were used to investigate polarization characteristics of the THz-TDS system.
