Abstract: We describe a film of highly-aligned single-walled carbon nanotubes that actsas an excellent terahertz linear polarizer. There is virtually no attenuationstrong absorption when the terahertz polarization is perpendicular parallelto the nanotube axis. From the data we calculated the reduced linear dichrosimto be 3, corresponding to a nematic order parameter of 1, which demonstratesnearly perfect alignment as well as intrinsically anisotropic terahertzresponse of single-walled carbon nanotubes in the film.
