Transmission and propagation of terahertz waves in plastic waveguides
B. Ung and M. Skorobogatiy, École Polytechnique de Montréal, Canada
Polymer optical fibers provide a versatile solution for guiding terahertz (THz) radiation. The key benefits of this technology include: the abundance of the low-cost relatively low-absorption-loss polymers; the ease of fiber preform fabrication by molding, drilling, stacking and the use of other standard polymer processing techniques; and finally the advantage of simple fabrication method by fiber drawing at relatively low temperatures. In this chapter we review the latest developments in the design, fabrication and characterization of plastic-based optical fibers for guiding of THz light. ...
