Abstract

Terahertz pulse propagation in hollow optical fibers is investigated by using terahertz time-domain spectroscopy. From evaluation of transmission loss spectra of hollow optical fiber, it is found that TM11 mode propagates as well as TE11 mode that is the lowest order mode in terahertz metal-hollow fiber. Short-time Fourier transform is also applied for investigation of mode properties and as a result, it is confirmed that the interference peaks in the loss spectra are due to mode mixing in hollow optical fibers. Finally we performed a terahertz wave remote spectroscopy using the hollow optical fiber and acquired a clear transmission spectrum of the theophylline.
