ABSTRACT:
The present invention relates to a plastic photonic crystal fiber for terahertz wave transmission and a method for the manufacturing thereof. More particularly, the present invention is directed to a plastic photonic crystal fiber that can be easily manufactured and has low loss characteristics to be used as a waveguide of terahertz waves. The plastic photonic crystal fiber includes a crystal defect component having a longitudinal axis and a photonic crystal component surrounding the crystal defect component. The photonic crystal component has an array of a plurality of plastic elements having longitudinal axes and forming a 2-dimensional photonic crystal structure with a predetermined lattice constant. Further, the plastic photonic crystal fiber of the present invention can be used as a preform from which a plastic photonic crystal fiber for an optical communication (400–800 nm) can be drawn.
