Abstract

We report on a drawing-ratio dependence of the refractive index difference between the two optic axes (Δn) of poly lactic acid films in terahertz frequency range. We found that Δη can be controlled in a range of 0-0.04 by changing the drawing ratio. The result shows that we can design a terahertz wave plate with arbitral retardation, which will be useful for establishing polymer-based terahertz optical component with low cost and easy implementation in mass production.
