Abstract
Terahertz radiation, with wavelengths from 30 to 3000 microns, has big potential for applications such as biomedical sensing, noninvasive imaging and spectroscopy. Current researches on photonic crystal fibers as THz waveguide has been widely presented, but the sorts of waveguide usually need special fabrication technique and always be difficult to get perfect structure. We report on a new type of polymer photonic crystal fibers for low-loss guidance of THz radiation with general fabrication technique. The use of the cyclic olefin copolymer (COC) Topas, results in THz fibers with relatively low loss and low material dispersion in the THz range. We manufactured a class of THz waveguides with different structures. Then we use a THz time-domain spectroscopy system (THz- TDS) to characterize the Material loss and index of refractive of the waveguides.
